High Level Science Products are observations, catalogs, or models that complement, or are derived from, MAST-supported missions. These include Hubble (HST), James Webb (JWST), TESS, PanSTARRS, Kepler/K2, GALEX, Swift, XMM, and others. HLSPs can include images, spectra, light curves, maps, source catalogs, or simulations. They can include observations from other telescopes, or data that have been processed in a way that differs from what's available in the originating archive. Use the filters below to discover HLSP.

A Hubble Space Telescope gallery of merging galaxies (MERGGAL)

The HST 18th anniversary press release contains a large gallery of interacting and merging galaxies. In association with this press release, seven of these objects have been made available as MAST High-Level Science Products (HLSP). These data were originally acquired under HST programs 6276, 10592, 11091, 11092, 11095, 11956, and 11994.

Hubble Space Telescope ACS mosaic images of M51, the Whirlpool Galaxy (M51)

In January 2005, the Hubble Heritage Team obtained a large four-color mosaic image of the Whirlpool Galaxy NGC 5194 (M51), and its companion NGC 5195, with the Advanced Camera for Surveys (ACS) onboard the Hubble Space Telescope (HST). The resulting color composite image was released to the community on April 25, 2005 to celebrate Hubble's 15th anniversary. Since the M51 mosaics produced by the Hubble Heritage Team represent a significant investment of expert processing beyond the standard archival products, these drizzle-combined FITS have been released simultaneously as a High Level Science Product via MAST.

NICMOS Legacy Archive PSF Library (LAPL) And Cirumstellar Environments (LAPLACE)

NICMOS coronagraphy, with well-matched template Point Spread Function subtraction, probes the closest environments of occulted targets with the highest imaging sensitivity in intrinsically high contrast fields at the smallest radial distances afforded. To obtain the best results, suitable template PSFs required to produce high-fidelity, photometrically robust, high contrast coronagraphic images are needed. To remedy this situation, the team undertook a rigorous, homogeneous, and complete recalibration and analysis of the full archival set of raw NICMOS coronagraphic images (through HST Cycle 15) to create a Legacy library of template PSFs.

Kepler Objects (KEPLER_HLSP)

This HLSP contains the detrended Kepler light curve and ground-based follow-up data (radial velocities and line bisectors) for Kepler's first five exoplanet discoveries.

Astrometrically Calibrated Images of Cluster Regions Observed by K2 (K2SUPERSTAMP)

The K2SUPERSTAMP project consists of image data on four open clusters observed by the NASA K2 Mission. The clusters are M35, M67, Ruprecht 147, and NGC 6530 -- the Lagoon Nebula Cluster (referred to here as the Lagoon). While data for these regions were previously released by K2, it consisted of small (~50x50) target pixel file stamps. In this release, the K2SUPERSTAMP team have stitched together all small stamps for each region to create one larger image for every epoch, and subsequently fit a world coordinate system (WCS) solution to each resulting FITS file. With these products it is now possible to identify any and all stars in these open cluster regions via their right ascension and declination. Most stars that fell across the edge of the target pixel files now have spatially continous data. Each file corresponds to a single timestamp at the 30 minute long cadence of K2, and may be read in via standard FITS handling programs (e.g. IRAF and Python/astropy). This format enables the production of time series photometry for cluster stars.

Survey of High Redshift 3C Radio Galaxies and Quasars (HZ3C)

Hz3C is a project that observed 22 high-redshift (1 < z < 2.5) 3C radio galaxies and QSO's with HST WFC3 in the rest-frame UV and IR. A custom data reduction strategy is used to remove cosmic rays, persistence signal, and other data artifacts to produce high-quality images of the targets and their local environments. Both F606W and F140W observations are available in FITS format. The observed targets include those with regions of UV emission indicating active star formation.

The HLA Star Cluster Project (HLASTARCLUSTERS)

Compact star cluster catalogs are presented for 20 nearby, star-forming galaxies using observations from the Advanced Catalog for Surveys (ACS) and source lists generated by the Hubble Legacy Archive. A typical cluster luminosity function can be approximated by a power-law, with an average value for the index of -2.37 and rms scatter = 0.18. The uniform database provided by these HLA catalogs results in a small scatter (0.5 magnitude) in the correlation between the magnitude of the brightest cluster (M_brightest) and log of the number of clusters brighter than M_I = -9 (log N).

Hubble Heritage Project (HERITAGE)

The Hubble Heritage Project and MAST maintain this repository of high-level science products associated with some of the Heritage press releases. These are the scientific data (in FITS format) used to create the Heritage color composite press release images. The data has been expertly prepared, significantly beyond the standard pipeline processing. This usually involves careful image registration, combination, and cleaning via drizzling, making it a ready for further scientific analysis and educational use. These data are typically made available at the time of the associated press release, and each include a README file with data reduction details. Their inclusion as MAST High-Level Science products (HLSP) also means these data can be found via MAST archive queries.

Galaxy Halos, Outer disks, Substructure, Thick disks and Star clusters Survey (GHOSTS)

The GHOSTS survey (P.I. Roelof de Jong, Space Telescope Science Institute) provides HST analysis of extra-planar stellar populations of nearby disk galaxies (programs 9765, 10523, and 10889). The survey provides HST analysis of extra-planar stellar populations of nearby disk galaxies. Using deep ACS, WFPC2 and WFC3 images the project targets several edge-on galaxies covering a range of masses (Vrot = 80-260 km/s).

Formation History of Ultra-Faint Dwarf Galaxies (FHUFD)

FHUFD (HST Proposal 12549) is a deep, high-precision, photometric survey of six ultra-faint dwarf galaxy satellites of the Milky Way, in order to discern any cosmologically-driven synchronization of their formation histories. For six ultra-faint dwarf satellites of the Milky Way (Bootes I, Coma Berenices, Canes Venatici II, Hercules, Leo IV, and Ursa Major I), the team provides ACS photometry, astrometry, and co-added (drizzled) images. The photometry and images are in two bands: F606W (broad V) and F814W (I), using the STMAG photometric system. The astrometry is given in equatorial coordinates (degrees, J2000). The drizzled images have a scale of 0.03 arcsec/pix. The images from each pointing are contained in their own FITS file. Each galaxy also has a single catalog file containing the point sources detected in the images.

ATLAS9 Model Atmosphere Database (BOSZ)

BOSZ stellar atmosphere models are based on ATLAS-APOGEE ATLAS9, and cover a broad range of effective temperature, surface gravity, metallicity, carbon abundance, and alpha-element abundance. Versions at different instrumental broadenings are provided. The new BOSZ LTE models have been fit to O,B,A,F,G stars observed with HST/STIS, and those results are compared to fits for the LTE grid from Castelli & Kurucz (2004).

Brightest of Reionizing Galaxies (BORG)

The Brightest of Reionizing Galaxies (BoRG) observations were first obtained in HST Cycle 17 in program GO 11700 (PI: Michele Trenti) and continued in Cycle 19 with program GO 12572 (PI: Michele Trenti). BoRG is an ongoing pure-parallel program that obtains WFC3 imaging in four filters (F606W, F098M, F125W, F160W) on random sightlines at high Galactic latitudes (|b| > 30 degrees). BoRG also assimilates data from the similar Hubble Infrared Pure Parallel Imaging Extragalactic Survey (HIPPIES) pure-parallel program (GO 11702; PI: Yan) as well as the coordinated parallel observations acquired as part of the Cosmic Origins Spectrograph (COS) GTO program (GO 11519, 11520, 11524, 11528, 11530, 11533, 11534, 11541, 12024, and 12025).

Archive of Nearby Galaxies: Reduce, Reuse, Recycle (ANGRRR)

A team headed by J. Dalcanton, K. Gilbert, and B. Williams have produced an archive of stellar photometry for non-Local Group galaxies within 5 Mpc, based on primary and parallel wide-filter UV and optical observations taken with ACS/WFC or WFPC2. This first release includes the ANGRRR Photometry Repository for 71 galaxies within 3.5 Mpc, which contains binary FITS tables of the stellar photometry. Also included are associated reference images and binary fits tables of the raw photometry.

Deep Optical Photometry of Six Fields in the Andromeda Galaxy (ANDROMEDA)

Using the Advanced Camera for Surveys on the Hubble Space Telescope, Thomas Brown (STScI) et al. obtained deep optical images reaching well below the oldest main sequence turnoff in six fields of the Andromeda Galaxy. The fields fall at four positions on the southeast minor axis, one position in the giant stellar stream, and one position on the northeast major axis. These data were obtained as part of three large observing programs (9453, 10265, 10816) designed to probe the star formation history of the stellar population in various structures of the galaxy.

The ACS Survey of Galactic Globular Clusters (ACSGGCT)

The ACS Globular Cluster Treasury program (PI: Ata Sarajedini, University of Florida, HST Program 10775) used the ACS/WFC instrument on board the Hubble Space Telescope to obtain uniform imaging of 65 of the nearest globular clusters to provide an extensive homogeneous dataset for a broad range of scientific investigations. In June 2013, six new clusters were added to the archive from the HST program 11586.
