HSTPAEC - HST Planned and Archived Exposures Catalog
This database table provides a summary of both planned and completed HST observations. Much more information can be obtained about each exposure, and the data themselves can be retrieved, using STScI's Multimission Archive (URL is http://archive.stsci.edu/hst/) or STScI's Archive Web Interface (URL is http://archive.stsci.edu/hst/search.php). Note that a number of solar system and other objects have 0 values for their 2000 equinox RA and declination coordinates in the original HST table and hence also in this HEASARC database.
This HEASARC version of the HSTPAEC will be updated on a regular basis, usually within one month of the data files on the STScI Web site (URL http://archive.stsci.edu/hst/paec.html) being updated.
The name of the target. In some cases, the name may have been truncated to 16 characters, which is the maximum space allowed for this field in this catalog.
The right ascension of the target in the default equinox.
The declination of the target in the default equinox.
The galactic longitude of the target.
The galactic latitude of the target.
The instrument configuration.
The instrument operating mode.
The apertures used. Multiple apertures are delimited by semicolons.
The spectral elements used. Multiple elements are delimited by semicolons.
The "central" wavelength of the observation, in Angstroms (AA).
A flag indicating whether corrective optics were used (i.e., COSTAR, WFPC2), where 'T' means that they were and 'F' means that they were not.
The length of the exposure time, in seconds.
The unique number assigned to each proposal.
This field has been added by the HEASARC to uniquely differentiate between multiple exposures of the same target in a given proposal.
The proposal cycle for the observation.
The dataset name, if the observation has been completed, will uniquely identify the data for the given exposure; otherwise, it will contain "PLANNED" if the observation has not yet been made.
The date on which the observation becomes/became public.
