The Multimission Archive at STScI (MAST) Newsletter disseminates
information to users of the HST, FUSE, IUE, Copernicus, EUVE, HUT,
UIT, WUPPE, IMAPS, BEFS and VLA-FIRST data archives supported by MAST.
Inquiries should be sent to
archive@stsci.edu.
StarView v6.0 is a Java application to execute archive searches and
data retrievals. StarView v6.0 will replace StarView 5.4a, the current
xwindows interface. StarView v6.0 will provide all of the essential
capabilities of the xwindows version of StarView, and it will be
available on any platform that supports Java, including Solaris and
Windows. Version 6.0 will also have enhanced capabilities in
customizable search forms and a more controlled screen environment.
Because of its Java origins, the StarView ``look and feel'' is a little
different from the current StarView, but the components should be
recognizable to our archive users. We plan a public downloadable
version to be released in June, 2000. We are looking for volunteers to
use the prototype and to try the public release. If you are
interested, please contact us at
archive@stsci.edu.
The Extreme Ultraviolet Explorer (EUVE) MAST search script (available
at
http://archive.stsci.edu/euve), which allows users to search the
EUVE catalog of observations and download EUVE data from HEASARC, now
includes preview images. EUVE 1-D quick-look spectra for most EUVE
sources were extracted from the permanent archive 2-D images using the
standard EUVE IRAF routines, and written to gif files using IDL
plotting routines. Plots include spectra from each spectrometer: the
short wavelength spectrometer (SW; 70-190 Angstroms), the medium
wavelength spectrometer (MW; 140-380 Angstroms), and the long
wavelength spectrometer (LW; 280-760 Angstroms). If more than one
spectrometer acquired data, a combined 70-760 Angstrom spectrum is
available. Preview spectra are accessible from the result page of the
search script, as currently done for IUE and other missions. In
addition to the images, users can also download ASCII files of
wavelengths and calibrated fluxes, and/or display listings of FITS
keywords.
The MAST ``quick search'' routine performs a search of the MAST archive
for a given object based on its name or coordinates. The routine has
been recently expanded to search all MAST missions, including some the
latest additions: the Berkeley Extreme and Far-UV Spectrometer (BEFS),
the Interstellar Medium Absorption Profile Spectrograph (IMAPS), and the
Far Ultraviolet Spectroscopic Explorer (FUSE). The result page now
includes links to preview spectra and ASCII files of wavelengths and
fluxes for the International Ultraviolet Explorer (IUE), the Hopkins
Ultraviolet Telescope (HUT), the Wisconsin Ultraviolet Photo-Polarimeter
Experiment (WUPPE), BEFS, and EUVE. The ``quick search'' page is
available at http://archive.stsci.edu/quick_search.html. To use, just
enter a SIMBAD-friendly target name or the target coordinates as
ra,dec. The search results page will show up to 10 entries for each
mission having observations of the requested target, with a link to each
mission search script for displaying additional entries.
MAST provides access to a set of highly processed datasets from
missions supported by MAST at
http://archive.stsci.edu/prep_ds.html.
These datasets have undergone special processing by their authors and
are likely to have interest for several purposes, for example, spectral
atlases obtained from GHRS and IUE data. In all cases these data are
provided both as ASCII tables and as figures. The latest additions
include: (1) a nearly continuous time series of spectra in the
wavelength region including the SiIV 1394, 1403 Angstrom doublet for
the B0.5e star gamma Cas over nearly 22 hours and (2) an IUE atlas of
stellar spectra by Wu, Mo, and Crenshaw. The gamma Cas data were
obtained through the GHRS Large Science Aperture and with the G160M
grating and read down in rapid mode. Thus, the spectra may be co-binned
in wavelength in order to construct a light curve (the known "Geomagnetic Induced Motion Problem" (aka GIMP) has been corrected fo
r). The data are a unique time series on a
hot star for the GHRS. The Wu et al. atlas comprises low dispersion
spectra of 476 "normal" stars and 38 subdwarf and white dwarf stars
reduced through NEWSIPS processing. We now have quite a complement of
digitized UV atlases of bright stars which can be used for a variety of
purposes. We invite you to take a look!
The entire series of NASA IUE Newsletters has been scanned and placed
online. These 57 volumes, spanning 1978 to 1997, provided the primary
source for user information, calibration and processing reports, and
other information during the lifetime of IUE. We plan to provide a
linked index to the most relevant articles within the next few weeks. In
addition, you can browse through the table of contents of each volume,
locate an article, and view it in PDF format from
http://archive.stsci.edu/iue/newsletters.html.
