For "Guider Search":
The value of TARGNAME in a guider camera FITS header is taken from TARGNAME in the corresponding science file. This value may or may not be resolvable into a sky position by NED or SIMBAD. Queries on TARGNAME search for case-insensitive substrings of the entries in the TARGNAME keyword, without any name resolution.
For "Basic Search" or "More Search Options":
At the time of observation, the target name included in the table of
scheduled observations is recorded in the TARGNAME FITS keyword. The
target often corresponds to an object name that NED or SIMBAD can
resolve into sky coordinates.
Queries on TARGNAME search for case-insensitive substrings of the entries in the TARGNAME keyword, without any name resolution. For files where TARGNAME is blank (common in calibration files), KOA searches the OBJECT keyword, entered by observers at the telescope and intended for their records and often does not correspond to a name that NED or SIMBAD can resolve into sky coordinates. For NIRC2 and OSIRIS data, the string search is performed on both TARGNAME and OBJECT, though only OBJECT is displayed in the results since for these instruments, the OBJECT keyword is more likely to contain the observer's name for the science target. Searches on TARGNAME are particularly useful for finding Solar System objects.
KOA performs no validation on the returned data, and so TARGNAME searches may return data that do not contain the desired target. Be sure to examine the quicklook images of the returned records and only select the desired data before proceeding with analysis.
