[daip] RE: FRPLT and POSSM with SHIFT

[Vycheslav Slysh]

Leonia,
thank you very much for correcting AIPS tasks. The new FRPLT provides an
option of the search for position shift. This is a very useful option which
can be used for determination of absolute coordinates as an alternative to
SAD. However my first attempt with the 'search shift' option
was not successfull: it did not produce any output. May be I have to do it
more carefully, or there is another bug in FRPLT.
Once again,
happy New Millennium Year!
Slava
