Fixed SPRs in core v11.13.2:

PHS:

SPR 774 To validate a certain pointing for perigee passage, the visibility was being checked using constraints applying to observation periods. These constraints include eclipses, which hold for the entire spacecraft. During an eclipse no pointing is valid for observation, and therefore, no valid perigee passage could be found for revolution 434. It seems that the perigee pointing from the PSF is not (re-) validated by the ISOC software, and therefore rev. 434 could be planned with the ISOC system v. 12.3.4. This version of core fixes the problem and appropriately applies non-observation period constraints when checking perigee passage validity.

Fixed SPRs in fdserver v1.6:

SPR 774 See release notes for core v. 11.13.2. Perigee passage validation requires checking the visibility of a pointing during the perigee period, by applying the constraints applicable to non-observation periods. The interface only allowed visibility calculation using observation period constraints. The interface has therefore been extended.
