Execute "dtree" to see all the volumes possible. From the code you can find
what names are available for volume collections. Use "grep" to find the
relevant routines for each of these.

The defined volumes: (This is from gsimpar.inc)

parameter (all = 1)
parameter (cc = 2)
parameter (dc = 3)
parameter (ec = 4)
parameter (ec1 = 5)
parameter (sc = 6)
parameter (st = 7)
parameter (toru = 8)
parameter (mini = 9)
parameter (foil = 10)
parameter (ptg = 11)
parameter (other = 12)
parameter (max_detector=12)

character*4 det_name(max_detector)
data det_name/'ALL' ,'CC' ,'DC' ,'EC' ,'EC1' ,
1 'SC' ,'ST' ,'TORU','MINI','FOIL',
1 'PTG' ,'OTHE'/

The volume you missed was OTHE, which collects a bunch of stuff not related
to the active detector parts.
