Telescope Control without Moving Antenna

Some observing modes can be used without moving the antenna, There are two possibilities:

Use Telescope Control in "Special Mode"

last checked: 2009-10-07 (wb,hu)

You can restart the telescope control in a special mode that does not send any command to [AntennaMountDrive] .

For those observing modes where the duration of a subscan is controlled by AntennaMountDrive, the duration is fixed to 30 sec.

In order to use this special mode, do under account mrt@mrt-lx1:

cdCoordinator                   # set def directory
./goKill                        # stop current control processes
export ncsAntennaMDOffline=yes  # set environment variable ncsAntennaMDOffline to anything you like
./go

To get back to normal observations with antenna mount drive:

./goKill
unset ncsAntennaMDOffline
./go

Note:

Put Axes in "Manual Control Mode"

Anchor(ManualControl Another possiblity is that the operator puts the control of axes az,el in manual mode. This mode does NOT require export ncsAntennaMDOffline=yes In this case, only observing modes that do not need antennaMD for their synchronization can be used. The only observing mode currently possible is a calibration without sky.

Bolometer absorber maps

Put the telescope control in the "special mode" described above.

/!\ Don't forget to remove completely the absorber (one part can be left inside) to start astronomical observations.
