Method for calibrating your data

It is the recommendation to use the mean $\mathrm{FCF_{beamequiv}}$ values presented in the previous section to calibrate your data. However, if it is desired to produce an individual FCF from the night of a particular set of science observations, then the method is described here.

1. Reduce the selected calibration observation using the dimmconfig_bright_compact.lis config file.
2. Use PICARD's recipe SCUBA2_FCFNEFD on your reduced calibration observation. This will produce information to the screen and a logfile log.fcfnefd with the FCFs as mentioned above, and an NEFD for the observation. PICARD by default uses fixed FCF's to calculate the NEFD. (450μm: 400 Jy/beam/pW and 850μm: 500 Jy/beam/pW). If you wish to get an NEFD using the FCF calculated for the individual calibrator you are reducing, add USEFCF=1 to your parameter file.
3. Take your selected FCF and multiply your map by it using KAPPA cmult.
