An initial release of the z.MAST Portal enables searching of the GOODS and CANDELS Hubble datasets through parameters focused on galaxy evolution. This new entry point is designed to enhance access, increase discoverability, enable visualization of related data, and aid in HST and JWST observation planning. Feedback is welcome as more features and datasets are added in the future.
A number of MAST staff will soon be attending the 2020 Winter AAS Meeting in Honolulu, participating in a number of workshops, demos, posters, and other sessions. Come visit us at booth #213!
New High-Level Science Products include a collection of postcards and software to extract TESS FFI-based light curves for individual targets, and UV photometry for a selection of open clusters. Updates include new TESS light curves for open cluster members from Sectors 8-11, new HST global maps of Uranus, and new CALSPEC reference files and galaxy SED templates.
Hubble imaging data from the WFC3 and ACS instruments are now receiving updated astrometric information by applying corrections from both the Hubble Guide Star Catalog and Gaia Data Release 2.
The first four years of data obtained by the Kepler spacecraft are available as an Amazon Web Services (AWS) Public data set. Details on which data products are available and how to use astroquery to obtain a light curve file from the s3 bucket are provided.
The first three sectors of Northern Ecliptic Hemisphere observations are now available through MAST, along with an update to announcements of upcoming TESS releases.
K2 Campaigns 6 and 7 re-processed data are now available across all MAST services, and include mission-produced short cadence light curves for the first time.
New High-Level Science Products include a collection of TESS light curves from open cluster members, a set of TESS light curves using PSF-based extractions from the 47 Tuc field, and a UV catalog for portions of the Kepler field. Updates include multi-band catalogs of the GOODS-N field from the CANDELS team, new HST maps of Neptune from OPAL, and new lens models for the RELICS collection.
The Hubble ACS team has provided new files that significantly revise the absolute flux calibration of the Solar Blind Channel imaging Modes. These updates have been included in ACS online tools, and newly-downloaded files from MAST will contain the updated photometric calibration header information.
STScI is working to transition the production of Hubble Legacy Archive (HLA) products to its standard data production pipelines. This will ensure the new Hubble Advanced Products (HAP) will always have the most recent reference files and pipeline calibrations.
The HCV provides the deepest catalog of variable sources to-date, assembled using data from the WFPC2, ACS, and WFC3 instruments on the Hubble Space Telescope. More than 80,000 candidates extend down to magnitude 27, with multi-filter variability detected in over 10% of the sources.
After completing a year of observations, TESS mission data available at MAST include all data products for the Southern Ecliptic Hemisphere, multi-sector light curves, and transit vetting reports for many targets. Recent updates also include a set of simulated TESS data for pipeline testing, and new tutorials for data access and analysis.
Two new High-Level Science Products include a collection of spectral energy distributions for over 40 AGN derived from multiwavelength data taken with a number of different observatories, and a study of 161 saturated K2 targets using scattered-light to calculate light curves for each object.
A new web interface and scriptable API provide easy yet powerful access to the HSC.
New High-Level Science Product collections include a survey of the COSMOS field, catalogs of Frontier Fields sources, STScI spectral references, and reprocessed spectra for an AGN target. Updates were also added to K2SFF, and new global maps for Jupiter and Saturn.
