[evlatests] An interesting observation ...

[Rick Perley]

    I'm reducing data taken by Michael a couple days ago, which includes 
observations made with the sub-bandwidth of 31.25 kHz, and 122 Hz per 
spectral channel.  The data are generally lovely (details to reported on 
later), and the bandpasses perfect -- with a curious exception...

    As a scroll through the bandpass solutions, I note that they 
progressively shift 'leftwards' as the antenna number increases -- the 
low-frequency filter cutoff is completely gone by the time antenna 28 is 
reached.  The shift, per antenna, is about 125 Hz.  Sounds to me like 
the fshift is not properly accounted for.
