Pointings Search Parameters
The Pointings search tool can be used to search either a pointings
table (containing one pointing entry per row) for a particular HST
instrument, or a view for a particular instrument containing
one HST observation per row. The "action" parameter determines the type of
search, namely "action=Search+Pointings for the first or "action=Search+Exposures"
for the second.
The instrument is specified with the "primary" parameter and may have the
values ACS,STIS,NICMOS,FOC,WFPC2, or WFPC2ASN.
The table below lists all the parameters available for
Where reasonable a range or set of valid values is listed.
Additional notes are included. If you click on the field name, a

The column labels below
are used in the search forms and search results whereas
the column names below
need to be specified for searches submitted as a GET request.
There are however some special cases as shown in the
examples, when coordinates
or filters are included in the search.
Note: fields below beginning with "pnt_" describe the pointing, while fields
beginning with "pntd_" describe individual observations. When searching the
pointings tables, only the "pnt_" fields are available as query parameters.
Exposure searches can use all the described fields.
