Greetings

In case people are wondering why I am wondering about these variables, I 
thought our GSIM variables came from the MySQL because of the input into 
the ffread card. Below is an excerpt of the GSIM help page for the 
varible of the magtype, which I think is related to the variable 
<http://clasweb.jlab.org/cgi-bin/caldb/cct.pl?hostnameaa=clasdb.jlab.org;hostnamebb=clasdb.jlab.org;runindexaa=calib_user.RunIndexg12;runindexbb=calib_user.RunIndexg12;runaa=56855;runbb=10;submit=477;mapdir=;mapget=>RUN_CONTROL_currents_torus 
<http://clasweb.jlab.org/cgi-bin/caldb/cct.pl?hostnameaa=clasdb.jlab.org;hostnamebb=clasdb.jlab.org;runindexaa=calib_user.RunIndexg12;runindexbb=calib_user.RunIndexg12;runaa=56855;runbb=10;submit=477;mapdir=;mapget=> 
stated in my previous email.

MAGTYPE 	2 	M 	magtype 	Set type of magnetic field used.
Arg1= magtype, Arg2= analytic torus field strength
Magtype=
      0       no torus or mini field
      1       simple analyPTGANGLEPTGANGLEtic torus
      2       torus from lookup table
      3       torus + mini from lookup table
      4       mini-torus from lookup table
Usually 3 or 2.




If you know how this works, or knows a GSIM expert on this, please 
inform me.
