Instructions (16.1.2001):
 

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

  •  

     

    total to 16.1.01:   0scans x 16subs x 10s x 1.5 =  0h + overhead
