| Description: Keyword values used in the HST planning software to define a moving target. These often provide easier-to-interpret information about a solar system target. Examples are "PLANET JUPITER", "TORUS JUPITER", "SATELLITE EUROPA", and "ASTEROID 216". These values are obtained from the FITS header of the _shf.fits or _spt.fits file, given as values of keywords TARKEY1, TARKEY2, etc. If no TARKEY keywords appear in the FITS header, this attribute should be nil with nilReason = "inapplicable". |
