The antenna offsets are expressed in a system described by the card
SYSTEMOF in the Antenna HDU. If its value is:
- projection, this means the offsets are radio-projected in
the current coordinate system, i.e. the system found at
; the offsets can be used ``as is'' in
CLASS,
- something else, e.g. horizontalTrue for calSky, the
offsets are not expressed in the correct frame and should be
recomputed to the desired sky coordinate system (CLASS does not
offer the possibility to express the reference in one system and the
offsets in another). ZZZ this is not yet implemented, warning for
now.
