Description
Difxcalc is a version of calc11 modified specifically for the
DiFX correlator. It is a replacement for the calc9.1
'calcserver' currently in use. To create difxcalc, all
of the Mark3 database handler calls were removed from calc11
and new input, output and initialization modules were
written and the flow of the program was modified
for correlator usage. Difxcalc takes as its
input the .calc files that are created in the difx
processing stream and directly outputs the .im
correlator model files. It can handle jobs with
multiple scans and multiple phase centers. Difxcalc
also contains near-field models, which will allow
easier correlation of spacecraft or other objects in
the solar system. We will outline the structure of
difxcalc and list the differences from the calc9.1
'calcserver' and from the calc11 database version.
Results of various tests and comparisons will also
be presented.
