Optional output (with flag -a) returns also the alignment tag (Y/N). Optional output (with flag -p) returns the slit position (x and y). This script can also be used to turn the corresponding wheel(s) to searched position(s) with optional flag -m. Note that this moves only the corresponding wheels, leaving other wheels as they were. Flag options: - -g <grism>
Searches the grism and the filter wheel with given <grism> e.g. "#4" - -s <sslit>
Searches the aperture wheel with given <slit> e.g. 0.75 - -f <filterID>
Searches the filter, FASUa and FASUb wheels with filter <filterID> e.g. 76 - -m
Turns the wheel(s) so that the searched optical element(s) is in the light beam - -d <wheel>
Displays the content of the wheel, <wheel> is the name of the wheel: filter/fasua/fasub/grism/slit (Cannot be used with flags -s/-g/-f) - -a
Prints out the alignment tag (Y/N) in the output - -p
Prints out the the slit position (x, y) in the output - -o
Prints out the 'Open' positions for every wheel. (Cannot be used with flags -s/-g/-f) - -h
Prints out help Usage example:
alfosc.optics -f 76 -g "#4" -s 0.75 -a -p
