um_scripts

Repo of scripts and code for the DESI telescope simulator - now in the Soares Santos lab organization 2.2!

Files

connect4.py ( DEPRECATED- please use run_ang.py): controls the execution of sequence (connection, remote_config, camera, mount, positioner, spotfinder, write_database) Usage:

[msdos@msslab01 ~/um_scripts]$ python3 connect4.py -c conf/getcurrent.ini

fao_seq.py: moves the positioners and reads args and remote_conf installed @ PBOX: /home/msdos/pclight/trenz

run_ang.py: formerly connect5.py - main movement code (!)

run_xytest2.py: more functions to run an xy test - main movement code (!)

XYtest.ipynb: code to translate between angular arm positions and xy coords, includes functions to switch between coordinate systems and to calculate move tables also includes some code and plots to check that this math is working

XYtestMovesFunction.ipynb: essentially the same as XYtest, but with a lot of the excess code removed

xylib.py: library built off of XYtest, all the functions to translate coordinates

fits look.ipynb: look at a fits (image) file

gen_movetable.ipynb: create a movetable and check plot to make sure it is safe

read_database.ipynb: various examples of looking at data from the database

fao_seq.py: moves the positioners and reads args and remote_conf

regions.reg: used for spotfinder code

tsmount.py: mount test move (?)

write_data.ipynb: for writing data to the database (?)

Check_a_picture.ipynb and TakePicsAndPlot.ipynb: exactly what they sound like

Pipeline

1. Install positioners: After manual install, get calibrations for the positioner

   • home_theta
   • home_phi
   • center of theta arc (block's hole center)

2. For sequence a. Check the position of positioners and spotfinder, WITHOUT moving, using*: python3 run_ang.py -c conf/getcurrent.ini

   b.set: cruise_speed, spinramp, dev_bb

   *run_ang.py was called connect5.py
