Instructions:
 

  • Try 3 sessions x 20 minutes of on-off observations: 16 subscans, 10sec, 34-53 wobbler throw  /nosym.
  • Do frequent  pointing (every 20 to 40 min, depending on stability), and about every hour a short onoff with 4 subscans a 10s
  • To be observed at best weather conditions
  • Please record under "Obs" the date, scan range, #scans x #subscans, total time, weather, and preliminary fluxes for each dataset.

    •
