Rebooting analog BE from SPdA
FMLO commissioning

CSV2016: Subref tilt offsets of DASH345/BAND8 (2016-08-25)†

↑

Tasks†

220GHz opacity <= 0.07 -> Subref tilt offsets in BAND8
220GHz opacity > 0.07 -> Subref tilt offsets in DASH345

↑

Preparations†

Basic checks

Record which kisa files are used for DASH345 and BAND8

aste16@aste-ms1: ssh astecntl@aste-1c "ls -l /cosmos3/aste/etc/kisag/{DASH3,BAND8}"
lrwxrwxrwx 1 astecntl astctl 12 Jun  3  2015 /cosmos3/aste/etc/kisag/BAND8 -> BAND8.150603
lrwxrwxrwx 1 astecntl astctl 12 Jun  1  2015 /cosmos3/aste/etc/kisag/DASH3 -> DASH3.150601

Check all subref parameters (dx,dy,dz,dtx,dty,dtz) are zero
Check Aspirin is working in the "WIND ON" mode

Tuning at EL=60.0 deg
- Tuning of DASH345/BAND8 for continuum observations
- Don't forget to record weather conditions

Subref tilt offsets in DASH345/BAND8†

Repeat cross scans toward Saturn with various (dtx,dty)
- Pointing toward Saturn
```
BAND8:   stx5b8.start
DASH345: stx5d3.start
```
- Repeat cross scans toward Saturn using the batch mode
```
BAND8:   ststb8.list (NOT stsbb8.list)
DASH345: ststd3.list (NOT stsbd3.list)
```
  - Don't forget to turn on auto-pointing in the QLOOKC GUI
  - Set AVERAGE = 1 in the QLOOKC GUI
Data reduction
- Still under preparation

Information†

Observers: Izumi
Site: Mitaka

Weather conditions (2016-08-25T:0130)

Temperature: -3.93 C
Humidity: 0.82 hPa
Wind: 1.76 m/s (251 deg)
220GHz opacity: 0.0499

220GHz opacity <= 0.07 -> Subref tilt offsets in BAND8

FMLO commissioning†

site: ASTE (sancho)
operator: ytamura

14:15 UTC - dash345 tuning with a standard position switching obstable for Ori-KL / 12CO(3-2)
- aste16/fmlo16/mORpsw.start
- following the instruction: https://sites.google.com/site/asteobservation/home/tuning
```
$ yfactor 1
Y=3.410471 dB 
$ yfactor 2
Y=3.579372 dB
==> looks good.
```

14:20 UTC - start observations
- aste16/fmlo16/mORpsw.start
- Again, a strange spectrum shows up!!!! ==> Check if the other table which succeeded in obtaining a correct spectrum...
- Tsys = 164 K (A1), 227 K (A3), which looks normal.

we have checked the contents of obstables, mORpsw.start and W51D3L.start, and found no intrinsic differences between the two. The latter of which has been confirmed to be the obstable that can obtain a correct spectrum toward W51. So I guess something goes wrong when tuning or spectrometer...

15:06 UTC - Tuning again...

  - This table is exactly the same as W51D3L.start, in which however the target coordinate is replaced with Ori-KL (because W51 has been set).
- We see a similar abnormal spectrum again, suggesting no pleblem with obstables, device setups, computational permissions.

Result:
- We again have a similar abnormal spectrum even with WHSF. (hmm..)
- Tsys on QLOOK is too low (60 K and 29 K for X1 and X3, respectively) while whsf_rsky reports normal Tsys ~ 300-500 K. This is however predicted by Okudasan (aste-unyo 03653) because of whsf_stab trouble.
- Let's give it another try to see if this happens again...

17:37 UTC - start WHSF observations (again)
- Obstable: aste16/fmlo16/wIRpsw.start
- Results:
  - Spectra of X1/X3 are abnormal.
  - Tsys on QLOOK are 299 K and 144 K for X1 and X3, respectively.
