- Tsys = 1800 K (A1)
- CO(4-3) is not detected. Expected intensity Ta* = 0.9 K, while noise level is ~ 1K, so it is not surprising if we don't detect the line. ==> quitting and moving on to GC tables.

21:XX UTC - mGCmpx1
- error: invalid acg integ_time

21:15 UTC - mGCmpx1
- OK, we could get the table started
- but, spectra shown in QLook don't change. Noise pattern doesn't change.
- Tsys spectrum determines the noise pattern??? ==> calib integ time 5s->10s

21:27 UTC - mGCmpx1
- spectrum doesn't change

21:49 UTC - mGCotx1
- normal OTF
- spectrum changes in time.

OK, this is just because a high Tsys. QLOOK virtually shows a Tsys spectrum with noise recorded in a last R-SKY measurement.

1:54 UTC - finished observations
- telescope has been put at az,el = -180, 60, set to STBY, and released the prio.
- I just restart cosmos for next observers, because aspirin doesn't work.
- OK, aspirin now recovered.
