    • Tracks each pixel of the maplet to define if its value should be considered

  • REAL*4 HT(-NTMP:NTMP,-NTMP:NTMP)

    • HT - Height. The height of the template at that location of the maplet. Used for trying to identifing shadow.

      • Calculated in this subroutine
  • DOUBLE PRECISION SP(3)
    • Sun vector
      • Calculated in this subroutine
  • LOGICAL EUSE
    • "Expanded T1" Flag for when to use the expanded threshold for DN.

      Is a flag set within lithos or lithosp using the 'x' option

      • Uses the ETOL variable
  • DOUBLE PRECISION ETOL
    • Expanded T1 flag variable.

      Is a flag set within lithos or lithosp using the 'x' option

      • Typically set to .025 (standard within the scripts for LITHOSP)
  • DOUBLE PRECISION FINV
    • Reports the fraction of invisible pixels within the maplet/image intersection
  • DOUBLE PRECISION DPIC_DLOC(2,3)
    • This subroutine computes the change in the image-space location (p,l) of a point (x,y,z) on a maplet as the point is moved in the maplet frame.

      • Changed within LOC2PIX that is typically called from this subroutine.

  • DOUBLE PRECISION DIDH
  • DOUBLE PRECISION DJDH
    • Rate of change for the position I and J in the picture
      • Calcualted in this routine and reported back to who called it
  • INTEGER Z0(2)
    • Center point to extract the data from the image.
  • INTEGER KK, ESZ
    • KK is a spacing parameter, which I think is based upon the maplet.
    • ESZ is the size of the array.
  • INTEGER DN(-1300:1300,-1300:1300)
    • The workspace of displayed DN for both the image and the maplet (template)
      • Set in this subroutine.

  • REAL*4 DNX(-NTMP:NTMP,-NTMP:NTMP)

    • The filled out data that we really want. Set in this routine.
