Test observations with WHSF and MAC†

Tasks†

• Reduce baseline instability of DASH345.

Preparations†

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.

Information†

• Observers:T. Ito
• Site:Mitaka
• Weather conditions
