The Archived Exposures Catalog (AEC) is an ASCII listing compiled from
the Hubble Space Telescope Data Archive database. This listing
provides a summary of completed HST science observations.
Exposures are included here after they have been archived at STScI.
The AEC files will be updated every month. The current version of the
AEC is complete to
Mon 03 Dec 2007 .
The complete list is sorted by
target position; the solar-system list is sorted by target name.
aper - Apertures used. Multiple apertures are delimited by semicolons.
spec - Spectral elements used. Multiple elements are delimited by semicolons.
wave - "Central" wavelength of the observation, angstroms.
c - Flag indicating whether corrective optics were used (i.e., COSTAR, WFPC2).
time - Length of exposure (in seconds).
prop - Proposal ID.
dataset - Dataset name. Uniquely identifies the data for a given exposure.
obsdate - Date on which observation was made.
release - Date on which observation becomes public.
The AEC provides summary information about each exposure in the HST
Archive. You can see much more information about each exposure and
retrieve HST data using either
or through the Archive Web interface.
