Summary

Check the magnitude, flux of the calibraiton light source with a new extension for the iLocator instrument.

The flux is checked using the magnitide and flux measurements by the soulSX.

The AO is set to be at close loop with a specific setup to have the same conditions before/after the fiber change. it shows mostly that there is the same flux.

Setup for the close loop: Bin1, 900Hz, 3l/D,600.
gain: TT0.15 HO1:0.05

The close loop is done through the FLAO GUI to the step close loop.

The AO lookup table has been modified to load to correct frequency (900Hz)

Detail.

Close loop before the fiber change.

The magnitude measured is 9.9 31 phtons per subaperture.
