1  FINDINGCHART 
      This procedure will plot a Finding Chart from the Guide Star Catalog
      by using the GSC command of GRAPHIC.

      This in turn will use the GSC CD-ROM of the correct hemisphere,
      using the GAG_CDROM and GAG_CDROM_MOUNT SIC logical names, that can
      be checked by the command SIC LOG GAG_CDROM and SIC LOG GAG_CDROM_MOUNT.
      It is up to the user to mount the GSC CD-ROM before using the 
      FINDINGCHART procedure  

      The procedure needs a position in the sky: the Center of Projection, 
      and a size (in arc minutes). The Center of Projection can be expressed
      in (RA,DEC) or (LII,BII). The format is:
      "HH:MM:SS.SS" for RA , "DD:MM:SS.SS" for DEC, LII and BII
      (But formats like HH.hhh or DD.ddd are also valid)
      The projection SYSTEM can be GALACTIC or EQUATORIAL (with optional
      epoch, default 2000.0).
      The size of square area plotted is :
          [>0 == limits are SIZE/2 -SIZE/2 -SIZE/2 SIZE/2 MINUTES]"
          [0 == 10 minutes  ;    <0 == manually use LIMITS command]"

      The user can change also the type and size of marker used by the
      program to plot stars. The markers ar polygons of Nsides, of
      style Mstyle:
         Nsides=0,1 Dots ; Nsides=2 Bar ; Nsides=3 Triangle ...
         Mstyle=0 Convex polygon;  Mstyle=1  Vertex  connected;
         Mstyle=2 Starred polygon; Mstyle=3 Filled polygon (Only for Nsides >3)

      Finally, the user can change the Limiting Magnitude of stars plotted,
      and can enable or disable the Identification of the stars.
