Description

The task evalcorr performs a simple evaluation of eposcorr amended source lists. The RAOFFSET , DEOFFSET and LIK_HOOD keywords are used assess the correlation as good (POSCOROK=T) or bad (POSCOROK=F) and set the value of SYSERRCC accordingly. The new parameters POSCOROK and SYSERRCC are written to the output as keywords. If the correlation is bad then the RA, DEC , LII and BII columns are used to overwrite the RA_CORR , DEC_CORR , LII_CORR and BII_CORR columns respectively.

The `force' command line options are mutually exclusive. For example the `-forceposcorok=Y -poscorok=N' will set POSCOROK to False but will not cause the _CORR columns to be overwritten.

The evaluation is:

POSCOROK = False if ( $(\sqrt{{RAOFFSET}^2 + {DEOFFSET}^2})>$ radiusthreshold OR LIK_HOOD $<$ likhoodthreshold) and True otherwise.

In the event that neither the 'amendinput' or 'withoutput' options are given no changes are made to the input but all messages are generated as if they were (so you can test what the program would do).
