Converting position switched data to Kelvins



    Posit ion switched data can be converted from spectrometer counts to kelvins using the cal values (see cnts to kelvins). The processing  includes:

Averaging over spectra.

    The processing takes averages over the posOn, posOff spectra as well as the calOn, calOff spectra.
The solution is to use the same rfi  mask for the on,off position data as the  cal on,off  data.

Example spectra: 3C48.

    On off position switching was done on 3C48 using the lband wide receiver. The setup was:
The plots show 3C48 in Kelvins across lband (.ps) (.pdf):
