*Test observations with WHSF and MAC [#m4c0e699]
**Tasks [#h8e992d5]
-Confirm reasonable spectra toward reference and pointing sources.
***Prepartions [#f40c10f7]
+ 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''>UsefulShortcuts#tcc7461d]].

***Test observations with WHSF and MAC [#tae3e12e]
- Observe M17SW and/or W51D with WHSF and MAC
#ref(Observing Log/2017-06-30/obs20170707.png,,50%)
+ Tune DASH345/BAND8
-- [[ASTE(google) Tuning Guide>https://sites.google.com/site/asteobservation/home/tuning]]
