PACS Spectroscopy Integration Estimates

• HSPOT-based June 2007
• Guesstimator-based January 2007

PACS Spectroscopy AORs

• Submitted Oct 2007: all nuc enuc strip single strip
• SDP for just N1097 and N4559 (4.5" and 10" steps)wavelength switching chopping
• SDP for just N1097 (12" steps) wavelength switching "half" of wavelength switching chopping "half" of chopping "half" of chopping with strip split into individual pieces
• SDP for just N4559 (12" steps) wavelength switching "half" of wavelength switching chopping "half" of chopping "half" of chopping with strip split into individual pieces

Preparing for Science Demonstration Phase (SDP)

• Chopping and Wavelength Switching overlays (JD's website)
• Notes
  Chopper throw options: 1',3',6'
  n1097 is 9.3'x6.3'
  n4559 is 10.7'x4.4'
  Primary SDP 15 Oct -> 30 Nov; Secondary 01 Oct -> 15 Dec
• Comments
  now using HSPOT v4.2
  wavelength switching now requires sky integrations
  n1097+n4559 time budget in hours: 20.6 (v3.4) -> 21.7 (v4.2 w/no offset in sky position) -> 23.4 (v4.2 w/offset); 49.7 (v4.2 w/chop)
  If flux estimates are not provided, bright continua and lines are assumed -> largest integration capacitors used, at risk of lower S/N for faint targets (p.3 HSpot changes doc)
  
• Questions
  Do we select "chop/nod" or "chop/nod (bright lines)"?
  Do we constrain the chop angle (or date of obs)?
  Can we longitudinally dither for strips?
