*Test observations with WHSF and MAC [#m92e5c0e]
**Tasks [#c4f414c3]
- Reduce baseline instability of DASH345.
***Preparations [#kfc5bcd0]
+ Basic checks
-- Make sure that DASH3 and BAND8 are linked to the following files

--- 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]].
