       SUBROUTINE  VISNP (PH,TH, JP,IT, NP,NT, T)
 C$    (Nearest Point)
 C$    Determine the coordinates of the line of sight joining  the
 C$    observer to the center  of the spherical coordinates.   The
 C$    arguments are:
 C$
 C$    (PH,TH)........Surface coordinates of nearest point.
 C$    (JP,IT)........Indices of nearest point.
 C$    (NP,NT)........Range of PHI, THETA indices.
 C$    T(3,3).........Orthogonal matrix defining rotation.
