Implemented SCRs in core v11.14.2:

OSS:

SCR 567 Before scheduling a slew, we validate that the from- and to-pointings of a slew are valid throughout the window in which the slew can take place. These validation means checking that both pointings are visible throughout the window. From this release on, this visibility check is performed with non-observational constraints, which allows eclipses. The effect is that between exposures, an eclipse is allowed to happen. A SOPS window in the PSF is required to introduce a gap in the slew window. This will prevent the slew from being scheduled during the eclipse.
