Astronomical Tests with VEGAS and Spectrometer

Overview

To test the 'fix' of running only a single channel through each of the dual channel VEGAS IF modules, we will run a few astronomical tests. In particular we will measure a continuum calibrator, and compare line strengths between banks of an X-band RRL.

Scan Information

  • 35-39 : Point and Focus on 0319+4130
  • 40 : Track on W3OH test, failure.
  • 41: Track Uranus
  • 42-43: Position switched observations on Uranus
  • 44-45: Uranus on/off for Sue Ann's visiting group of students
  • 46-47: Position switching on W3OH
  • 48-49: Position switching on W3OH (wrong target)
  • 50-51: position switch on W3 - mode 10 - all looks good
  • break for maintenance on KFPA
  • 52-56: Nonsense
  • 57-58: W3 60s position switch mode 4 (low cal)
  • 59-60: W3 position switch mode 4 (hi cal)
  • 61-62: W3 position switch mode 4 (lo cal - line shifted)
  • 63-64: W3 position switch mode 10
  • 65-69: 0207+6246 point and focus
  • 70-71: W3 position switch mode 2
  • 72-73: W3 position switch mode 2

  • 76-77: W3 position switch mode 21
  • 78-82: 3C48 point and focus
  • 83-84: 3C48 position switch mode 5 - Balance Issue
  • 85-86: 3C48 position switch mode 5 - 3.1 Jy flux density - exactly as predicted.
