TABLE  QsoTarget

Contains a record describing the attributes of each QSO Target object and also Target Surrogates to fill in the QsoConcordanceAll view.

This table is copied from the 'base' Target..PhotoObjAll Table. It has a row for each object flagged as a QSO (a candidate) and if no candidate exists nearby a Spec or Photo candidate then a 'surrogate' Target object is added -- the closest target within 1.5 asec of the QsoBunch head. If no such surrogate Target object can be found, we use the ZERO surrogate (literally, all fields are zero). The test for a target object being a QSO candidate is: primary target flags set to one of TARGET_QSO_HIZ |TARGET_QSO_CAP | TARGET_QSO_SKIRT |TARGET_QSO_FIRST_CAP | TARGET_QSO_FIRST_SKIRT The table also includes the id and summary statistics for matching FIRST and ROSAT objects if they exist, and zero otherwise Also includes the absolute magnitude based on Pen (1999) and Pei (1999) if a reliable reshift available from a specobj object in the bunch.
