I modified the Video.db file used by c1aux located in  /cvs/cds/caltech/target/c1aux.

I added the following channels to the db file, intended for either read in or read out by the digital camera scripts.

C1:VID-ETMY_X_COM
C1:VID-ETMY_Y_COM

C1:VID-ETMY_X_STDEV

C1:VID-ETMY_Y_STDEV

C1:VID-ETMY_XY_COVAR

C1:VID-ETMY_EXPOSURE

C1:VID-ETMY_GAIN

C1:VID-ETMY_X_UL

C1:VID-ETMY_Y_UL

C1:VID_ETMY_X_SIZE

C1:VID_ETMY_Y_SIZE

A better naming scheme can probably be devised, but these will do for now.
