SCULIB_ADD_DEMOD_EXPOSURE
- add demodulated data for an exposure into the
integration result
- Description:
- This routine adds the reduced demodulated data for an exposure in a
jiggle-sampled observation into the integration result.
The exposure can contain data either for all or part of ONE run
through the jiggle pattern or for several REPEATS of the entire jiggle
pattern. In the first case, the routine copies the exposure data into
the appropriate part of the integration arrays. In the second, the
integration data will be the average of the input exposure values and the
integration variance will be set equal to the exposure value if there
was just one valid measurement, or calculated from the dispersion of
the exposure data about the mean otherwise.
- Invocation:
- CALL SCULIB_ADD_DEMOD_EXPOSURE (N_BOLS, J_START, N_JIG,
J_REPEAT, J_COUNT, EXP_DATA, EXP_VARIANCE, EXP_QUALITY,
INT_DATA, INT_VARIANCE, INT_QUALITY, STATUS)
