MAST has begun to assemble a set of contributed highly processed datasets
or High-Level Science Products (HLSP) from missions supported by MAST.
These are datasets consisting of atlases, images, and/or
the data themselves which have been placed on the web either as final data products
or as appendices referenced in recent published papers. These data are in the
public domain and/or will soon be published.
The right ascension, in the J2000 equinox.
For WFPC2 Association data, the coordinates from the HST Science log were used.
For other missions, the coordinates specified by the hlsp developer were used.
The declination, in the J2000 equinox
For WFPC2 Association data, the coordinates from the HST Science log were used.
For other missions, the coordinates specified by the hlsp developer were used.
The angular separation in arcminutes between the observation
and the search center (the coordinates you're searching on). This is
calculated during the search, and the search results are sorted in order
of increasing angular separation. It has the nice effect of sending
parallels to the bottom of the list. (If you're interested in the parallels,
you can sort the list in descending order of angular separation.)
It also means that you can give a search radius like, say, 2 .. 8
to find all observations between 2 and 8 arcminutes from some position.
This could be used, for example, to exclude observations of the nucleus
of a galaxy, or the central star in a planetary nebula.
The filename or association name for the product. For WFPC2 association
data, the association name is displayed. For all other products, the entire filename
is displayed.
Type of file format. e.g. png = png image format, fits, txt = ASCII text format, ps = postscript, xls = Excel spreadsheet, jpeg = jpeg image format, gif = gif image format.
Journal reference is stored as a "bibcode", a format used by the ADS journal service
where the format is year, journal, volumne, page, first initial of the first author
Object as assigned by the creator of the HLSP except in the case of WFPC2 associations.
Objects for WFPC2 Associations are those designated by the original observer.
