Data in this table was reduced automatically in AIPS. Use caution when interpreting variations in quantities.

Follow links on Source/Band headings for Postscript plots.

Quantities displayed:
Flux - from SETJY (1995.2) or GETJY, to use in SETJY.
I Peak - peak I flux in map (mJy/beam). P Peak - polarized flux at I Peak (mJy/beam). %POL - PPeak/IPeak in percent.
PHAS - R/L Phase Difference (degrees) to use in CLCOR, also twice the EVPA on-sky. Of course, beware of sources with low (<0.5%) polarization.

Table Notes:

Flux set in SETJY shown with ± 0.

I Peak and P Peak quantities measured at peak in IPOL image. Watch for resolution effects due to configuration changes. Beware of calibration offsets for all sources in a date.

Values shown as X ± Y with X the average of IF 1 and 2 and Y half the difference between IF 1 and 2. Note 0137+331 and 1331+305 used as polarization angle references where Y = 0.0. Other entries with error of 0.0 have only a single usable IF in the data.

Statistical data for MEAN ± STDEV. Divide STDEV by SQRT N to get error in MEAN.
