As already mentioned, some of these parameters depend on previous settings, e.g. on the receiver bands and on other settings in the upper panels of the form.
In the
Products & Sideband Separation
field you can specify the combination of correlation products and the sideband separation mode. Only allowed combinations are listed, this depending on the receiver type and the choice of
Accumulation Mode
. When
ALMA_FAST
is selected for the accumulation mode,
AUTO_ONLY & NONE
is the only choice. Otherwise, i.e. when
ALMA_NORMAL
is selected, one or more choices are listed depending on the receiver type.
FREQUENCY_OFFSET_REJECTION
is the only allowed choice if the receiver type is SSB (Band 1 and 2) or 2SB (Band 3-8). Note that
PHASE_SWITCHING_REJECTION
is not listed: it is notsupposed to be used although ALMA has the function. For the DSB (Band 9 and 10) receiver type, the modes of separation are
PHASE_SWITCHING_SEPARATION
and
FREQUENCY_OFFSET_SEPARATION
as well as
FREQUENCY_OFFSET_REJECTION
.
The option
FREQUENCY_OFFSET_SEPARATION
is not available for the ACA correlator.
