Test observations with WHSF and MAC†

Tasks†

• Confirm reasonable spectra toward reference and pointing sources.

Prepartions†

1. Basic checks
   • Make sure that DASH3 and BAND8 are linked to the following files

     [aste17@aste-ms1 ~]$ ssh astecntl@aste-1c "ls -l /cosmos3/aste/etc/kisag/{DASH3,BAND8}"
     lrwxrwxrwx 1 astecntl astctl 12 May 31 07:58 /cosmos3/aste/etc/kisag/BAND8 -> BAND8.170531
     lrwxrwxrwx 1 astecntl astctl 12 May 31 07:33 /cosmos3/aste/etc/kisag/DASH3 -> DASH3.170531

     • If not, contact with CSV lead.
   • Set all subref parameters (dx,dy,dz,dtx,dty,dtz) zeros in the subref offset GUI.
   • Confirm that Aspirin is working in the "WIND ON" mode. If not, start it following the instructions in How to restart Aspirin.

Test observations with WHSF and MAC†

• Observe M17SW and/or W51D with WHSF and MAC

1. Tune DASH345/BAND8
   • ASTE(google) Tuning Guide
2. Adjust pointing toward W Aql
   • W Aql

     aste17:calib/WAQD3ph.start     W Aql 12CO(3-2) MAC-HIGH Pointing(5-points)
     aste17:calib/WAQD3pw.start     W Aql 12CO(3-2) WHSF(2G) Pointing(5-points)
     aste17:calib/WAQB8ph.start     W Aql 12CO(4-3) MAC-HIGH Pointing(5-points)
     aste17:calib/WAQB8pw.start     W Aql 12CO(4-3) WHSF(2G) Pointing(5-points)

3. Observe M17SW and/or W51D with WHSF/MAC
   • M17SW

     aste17:calref/M7cenM3.start    M17 12CO(3-2) MAC-HIGH PSW(center)
     aste17:calref/M7cenW3.start    M17 12CO(3-2) WHSF(2G) PSW(center)
     aste17:calref/M73mxM3.start    M17 12CO(3-2) MAC-HIGH OTF(x-direction)
     aste17:calref/M73mxW3.start    M17 12CO(3-2) WHSF(2G) OTF(x-direction)

   • W51D

     aste17:calref/W5cenM8.start    W51D 12CO(4-3) MAC-HIGH PSW(center)
     aste17:calref/W5cenW8.start    W51D 12CO(4-3) WHSF(2G) PSW(center)

• Confirm similar spectra to the following references
  • Past spectra in the ASTE obslog wiki
  • APEX - Comparison spectra → http://www.apex-telescope.org/heterodyne/shfi/calibration/standards/
  • APEX - Line pointing catalog → http://www.apex-telescope.org/observing/pointing/spectra/

• On 5th Jul. in Band8 WHSF observation, Pol1 has spurious.
• On 6th Jul. in Band8 and DASH345 MAC observation, Pol1 Tsys is bad and line intensity is too strong.
