Bill Cotton dove into the switched power table for the database
where I found switched power 'holes'. <br>
<br>
He reports that indeed, it is the table itself which has holes.
The missing data are *not* due to an error in BDFIn. The attaching
listing (from Bill) shows the actual data for one antenna, one
subband, at one band, for a single scan of 3C286. The missing
timestamps perfectly match the holes I found in the plots I used
which demonstrated the problem.<br>
<br>
So the problem is presumably at the stationboard level ...<br>

<pre>Rick,
See the attached listing (the 8th SW of X band is SW id 89). There
are indeed holes as you describe.
This listing should be all entries in the given time range, selected
antenna and Spectral window.
With a little cleanup, I'll put the task into the standard distribution
to insure it's never needed again.
