!     18-DEC-2002  B.K.  D.E.   This is an initial version of the Gains
!                               file for  eta  13:20   phi 1:8 only.
!                               It is based just on Geometry
!
!                        Recall that
!
!                        DAC_Code = 102 x (rerquired_gain + 0.25)
!
!
!      7-JAN-2003   D.E.    Set new gains for TT eta's 18,19,20
!                          
!               eta   Old EM Gain   New EM Gain   Old HD Gain   New HD Gain

!     23-JAN-2003   D.E.    Modify this file so that it loads up all 32 phi.
!
!      9-APR-2003   D.E.    Modify this file so that it covers just eta 17:20
