Routines
top source pp_azdif
result = pp_azdif(dphase, dinc, dema)
Given the angle between two directions (dphase) with angle from vertical
given by dinc, dema, returns the azimuth difference between them. All inputs
and the output are in degrees. This function is vectorized, so the 3 input arguments
can be of any dimension (must be the same for all 3), and that will be the dimension of the
result.
This function is complementary to pp_phase_angle.
Parameters
- dphase in required
The angle between the two directions (phase angle), in degrees.
- dinc in required
The angle between one of the directions and the vertical (incidence angle), in degrees.
- dema in required
The angle between the other direction and the vertical (emission angle), in degrees.
Examples
Taking incidence and emission in the same plane:
print,pp_azdif(30d0,40d0,70d0)
;0.0000000
print,pp_azdif(110d0,40d0,70d0)
;180.00001
print,pp_azdif(110d0,90d0,90d0)
;110.00000
