HSTAEC - HST Archived Exposures Catalog
Note that when the HEASARC ingested this catalog, (i) a number of entries were found with missing or null positional co-ordinates, i.e., RA and Dec values, which we have set to be at (RA, Dec) = (0,0) in equinox J2000, and (ii) 186 entries were found with clearly erroneous observation dates, e.g., Nov 17 1858, which the HEASARC has changed to null values.
The name of the target.
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 V3 position angle during the observation, in degrees. To compute the u3 roll angle from v3, simply add 180 degrees to it.
The field of view (FOV) configuration.
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 proposal ID.
The dataset name: this uniquely identifies the data for a given exposure.
The date on which the observation was made. (Note: There were 186 erroneous entrees of "Nov 17 1858 12:00AM" for this parameter. These erroneous dates were changed to null values).
The date on which the observation becomes/became public.
