Archiving spectral line data at AO

Data stored in the scan table (continued...)

 
• Correlator setup (repeated numband times):
• Subcorrelator bandwidths.
• number of channels
• correlator configuration (3,9 level, stokes, double nyquist)
• radar blanking.
• record integration time.

 
• Position information:
• Average azimuth,zenith angle encoder value for scan.
• Requested ra, dec at start of scan
• Requested delta ra, dec relative to start position.

    Non zero if mapping.
• Encoder error azimuth, zenith angle.

    Tells on average how far telescope was from the requested position.
