Troubleshooting guide

On the FLAMINGOS command line:
config.dither.kpno.pl Use to setup a sequence of images dithered about a common pointing
center.
config.exposure.pl Set filename, storage directory, exposure time, and number of reads, as
well as several descriptive fields.
config.filter.grism.decker.wheels.pl
Insert filter, grism and appropriate baffle on decker wheel.
config.mos.wheel Use to select the MOS wheel imaging hole.
dither.source.kpno.pl Executes data acquisition in the selected pattern.
fast.singleimage.pl Immediately take a single 1500 mS exposure time image.
more.singleimages.pl <n> Take n consecutive images with the present system configuration.
offset.kpno.pl <dra> <ddec> Offset telescope with respect to base pointing center.
relative.offset.kpno.pl <dra> <ddec>
Offset telescope with respect to present pointing center.
set.bias.pl Use to set the detector bias voltage; shortcuts for imaging (i) and
spectroscopy (s) may be typed to select common values.
set.exposuretime.pl Alternative way to set integration time (seconds) and number of reads
only.
set.filename.pl Alternative way to set the filename and data directory only.
singleimage.pl Take a single image with the present system configuration.
B. Wheel Setup for Imaging
FLAMINGOS has five wheels in its optical path, each containing various filters, pupil masks, and spectroscopic
slits. Hit the Update All Items button on the UFSTATUS GUI to determine the present location of the
wheels. In imaging mode the following configuration should be in place:
Decker Wheel (motor a) should be set to imaging.
MOS Wheel (motor b) should be set to imaging.
Filter Wheel (motor c) should be set to one of the following bandpass filters: J, H, K, Ks, JH,
HK.
Lyot Wheel
5
(motor d) should be set to 4-m.
Grism Wheel (motor e) should be set to open1.
If all you plan to do is imaging, then the you should not need to adjust the Decker or MOS wheels. If the MOS
wheel is not positioned correctly, use config.mos.wheel.pl to select the imaging aperture. Use
config.filter.grism.decker.wheels.pl to set the indicated wheels. The Lyot wheel should not need
to be adjusted. Each of these scripts will first query and then print the present motor positions.
The MOS script will query if you wish to change the setup; answering y will cause a list of 17 named
positions to appear. Type 10 to select the imaging hole. Next, the script prints out a detailed
information window, the last bit of which shows the desired move. Answering y at this point will
issue the wheel motion command.
For the filter/grism/decker script, type the motor name (c, d, or a, respectively) before acquiring a list
5 If the power to the motor controller has been cycled, the GUI will claim that the lyot wheel is at Hartmann1. The Lyot
wheel should have been set during the first engineering night of the FLAMINGOS run at the 4-m, and should not need
to be adjusted.
