Columns of table:

  1. label -- identifier for each optical object displayed on the chart(s) above.
  2. coordinates J2000 -- position on the sky of this optical object, pattern is hhmmss.s±ddmmss, which gives 1 arcsecond precision.
  3. dist asec -- distance (offset in arcseconds) of this object from the central galaxy, i.e. the center of the chart.
  4. angle E-N -- direction from the central galaxy to this object, N thru E, ie. 0 is up, 90 is left, 180 is down, 270 is rightwards.
  5. type -- short description of this object: Q=quasar, B=Bl lac, A=AGN, G=galaxy, S=star, X=X-ray source, R=radio source, 2=double radio lobes.
  6. R mag, B mag -- brightness of this object in red and blue colors respectively, 0=not seen in this color
  7. com -- comment on object: p=blue is POSSI-O violet, (no p)=blue is Bj green or similar, i=red is i, u=blue is u, v=variablility nominally detected, m=proper motion nominally detected, ?=inferred object, calculated from combining APM and USNO-A optical catalogs.
  8. R psf, B psf -- appearance of object in red and blue colors respectively, *=stellar, 1=fuzzy, 2=extended, n=no psf, x=not seen in this color.
  9. Name -- name of this object from the literature, or IAU name from X-ray/radio catalog.
  10. conf assoc -- confidence that this optical object is the true source of the X-ray or radio detection that we list with it. This is the published figure from the QORG catalog, except for XMM or CXOMP X-ray objects which are calculated using the identical technique as used in QORG.
  11. QSO pct -- confidence that this optical object is a QSO specifically, calculated as in (10) above.
  12. z -- the redshift of this object, from the literature. NBCKDE redshifts are photometric only, and rounded to tenths, e.g. 1.700.
  13. flux -- if a radio source, in mJy; if an X-ray source, in counts per hour as listed in ROSAT/CXOMP, XMM normalised to ROSAT (div by 3.5).
