        /SKY xOffsetC yOffsetC
        or
        /SKY NO                        ! do not do sky calibration

        Do a calibration subscan on sky.

        Real      :: xOffsetC          ! x-offset
        Real      :: yOffsetC          ! y-offset

        NOTES: with the usage /SKY xOffsetC yOffsetC, both parameters are required,
        but you can replace either parameter with * to leave it unchanged.
        The system for the offsets is selected through the option /SYSTEM.
