+gains
+=============
+The gains table contains nants complex antenna gains for nfeeds feeds and nsols solution intervals.

+======  ==============  =========
+offset  value           length
+======  ==============  =========

+(last 2 lines repeat nsols times)
+=================================
+
+
+bandpass
+========
+The bandpass table contains nchan * npol * nants complex channel gains.
+The value nchan is the sum of all channels in all frequency bands, npol=1 or 2.

+======  =================== ==================

+
+
+freqs
+=====
+A separate table "freqs" is maintained with the frequencies for each of nspec bands (or spectra).
+The item freq is the frequency for the first channel, df gives the channel spacing
