Measurement†

1. Start COSMOS3 and tune a receiver to be used
2. Login to COSMOS3 manager GUI with Group=asteXX (e.g. aste16) and Project=sbrfXX (e.g. sbrf16)
3. Adjust pointing
4. Run either of the following observation tables according to a planet and a receiver
    

   Saturn	DASH345	stsbd3z.start
   	BAND8	stsbb8z.start

Analysis†

1. Login to an analysis computer (e.g. aste-ms1/aste-mx3) with account=asteXX (e.g. aste16)
2. Rsync CONT data from the ASTE site

   asteXX@aste-ms1: ~/analysis/bin/cont_rsync.sh <project> <obs. table> <time> -link
   e.g.)
   asteXX@aste-ms1: ~/analysis/bin/cont_rsync.sh sbrf16 stsbb8z 201608150
   ...

3. Run lck_sbrfz.py

   aste16@aste-ms1> ~/analysis/bin/lck_sbrefz.py ~/sbrfXX/continuum/data/CONT. ... .LCK

• Example

  aste16@aste-ms1> ~/analysis/bin/lck_sbrefz.py -c 1 ~/test/continuum/data/CONT.jpzd3.aste16.linux16.201602050910.LCK 
  *** the following parameters are assumed
  ***   dummy scan duration = 10.0 seconds
  ***   start dz =  -3.0 seconds
  ***   stop  dz = +13.0 seconds
  # Plot fit results
  * -> ddz [sample] = 186.326212
  * -> ddz [mm]     = -0.018781
