MODIFY PROJECTION

        LAS\MODIFY PROJECTION Type [A0 D0 [Angle [DEG|RAD]]]

    Change the projection system of the current R observation, and optional-
    ly the projection center and angle at the same time. Type  "MODIFY  PRO-
    JECTION ?" for a list of supported projections.

    A0  and  D0  should be sexagesimal strings in degrees, except A0 in hour
    angle if coordinate system is Equatorial. Angle is the  desired  projec-
    tion angle, with its unit given just after (default degrees).

    If  an  argument  is absent or equal sign "=", it is left unchanged. The
    offsets are recomputed consistently according to  the  modified  parame-
    ters.
