Absorber measurements for the bolometer:
Moving the telescope; --> Find at what elevations you want to do the measurements, then find a real source in the sky at such elevations, for example let take W3OH.
>grep W3OH pool.sou --> W3OH EQ 2000 02:27:03.88 +61:52:25.5 LSR 0.0 FLUX 8.13 0.0 PROJECT CALIB
paKo> sou ABSORBER EQ 2000 02:27:03.88 +61:52:25.5 LSR 0.0 FLUX 8.13 0.0 PROJECT CALIB
paKo> onf 8 80
Repeat this at the different elevations changing the coordinates!
