Channels and CALIB

When one is self-calibrating a multi-channel data set, and one gives CALIB a BCHAN and ECHAN value, what is CALIB doing with the channels? Is it averaging them all before it calibrates?

If it is doing that, then why bother making a Channel 0 data set to calibrate off of? Simply because CALIB runs much faster if it doesn't have to deal with multiple channels? Is there something wrong with using a multi-channel data set to do the initial calibration (on the phase cal + flux cal sources?)
