Procedure: ShARCS Apeture Wheel
-
2018-07-05: If the power is cycled to the galil controlling
the ShARCS Aperture Wheel, it is necessary to issue the following
command:
modify -s saomot ctrl3aux=‘KIE=8;KPE=300;KDE=600’
These are new motor parameters that have not been put in software yet.
They should be the default before the next (2018-07-20--2018-07-26)
ShaneAO run.
-
Monitor the encoder counts for position of aperture wheel:
user@shard.ucolick.org > gshow -s saomot -c DWAPERGTE
For aperture wheel to be reproducibly positioned,
encoder counts must be within ±4 counts of the target encoder value.
-
For Spectroscopy, slit must be combined with matching filter.
For H-band spectroscopy: Filter#1 = H and Aperture = Slit-100um-H
For K-band spectroscopy: Filter#2 = K and Aperture = Slit-100mm-K
For Slit-100um-H, the target encoder value is: 0.
