    Hi Dana,

Great to hear that there's some slewing correction for TOFW going on.
For the TDC gains, it's not difficult to include into the database.
You just need to create an ascii file in the format readable by the 
calibration module and you'll be able to use the bratmain script that 
inserts the values into the DB. Here is a tyical ascii file (for TOFW):

****************************************** 
*  Calibration for Tof detector TOFW
*     Used events from run 2544
****************************************** 
*
* slat |  top TDC gain  | bot TDC gain 
*  ------------------------------------

down to 125

You should leave an empty line between the last line with a star and the 
first tube line, it is really important.


I made a version of the guide in pdf, it is at the same place.
