The idea is that variables will be methods for different bands. The idea is that variables will be introduced into SNAP, specifically two: CALON and CALOFF. These introduced into SNAP, specifically two: CALON and CALOFF. These can be defined by the band set-up procedures described above and can be defined by the band set-up procedures described above and used as $CALON and $CALOFF in procedures when the noise diode used as $CALON and $CALOFF in procedures when the noise diode needs to be controlled.needs to be controlled.
