... BITS sets the number of bits per sample for each baseband channel. ... Since an experiment will typically use the same number of bits per sample for all channels, it is usually only necessary to specify one value. If BITS is 2 , the first magnitude bit is placed on assigned track plus 8 for FORMAT = VLBA1:4 , on assigned track plus 4 for FORMAT = VLBA1:2 , and on assigned track plus 2 for FORMAT = VLBA1:1 . ... Same as baseband channel 1 if one or more are set. ... Example: BITS=1 . ...
