A method to solve PHYSICAL propagation problem in sci camera

[jsxiaxusheng]

In sh_8x8.yaml configuration, if using PHYSICAL in sci camera setting, the output detector PSF will be blank.

I found that that:

The returning variable of self.los.makePhase() method is efield, but the calcFocalPlane() function only use self.los.phase to calculate the intensity on the detector.

Therefore I suggest this change in SCI.py:

Line 99

self.interp_efield = numpy.zeros((self.FOVPxlNo, self.FOVPxlNo), CDTYPE)

Line 136-140

numbalib.bilinear_interp(
self.los.EField, self.interp_coords, self.interp_coords, self.interp_efield,
self.thread_pool, bounds_check=False)
self.EField_fov = self.interp_efield * self.scaledMask

I use this change solve the problem (but with no comlete testing).
