4. SUMMARY
Loaded the data into Miriad and data was inspected in Miriad with some problems noted below.
Fringes (amplitude & phase for baseline 2-5) are detected from the DATA of SWARM correlator
as well as of the legacy correlator but the spectral data from USB shows problems:
The scale (in amplitude) of SWARM chunk differs from the legacy chunks by a large factor (not scaled to Jy for SWARM data?);
the labelled frequency for the SWARM channels was offset from actual sky frequency (now corrceted);
the labelled channel separation was smaller by a factor of 2 (35 kHz)(now corrected).
