Pre-processing for usage of AIPS

AIPS is a popular software among the radio astronomical society. You have to re-format the NoRH raw data to be readable by AIPS. The program c2fits is developed for this purpose.

For 17GHz data,
unix% c2fits17 $<$ input $<$CR$>$
For 34GHz data,
unix% c2fits34 $<$ input $<$CR$>$
The format of input file (a template is given in ${NORH} /soft/c2fits) is as follows,

------------------------------------------------------------------

Note 1: The meaning of bypassing the amplitude calibration is that
        instead of computing the amplitude of the complex gains
        explicitly, the value 1.0 is used for all antennas. If the
        amplitude calibration is bypassed the amplitude smoothing
        time is ignored.

Note 2: If a fixed calibration interval is used, the smoothing time
        is ignored. It is assumed that the time standard for the
        fixed calibration interval is the same as that of the data
        interval.
