NAOMI Start-up Check list and daily DE checks

ØPerform a simplex: to optimise image quality

•Run the simplex (with AG7 visible light or Ingrid for infrared)

•Set WFS Integration Time to 25ms or 50ms

•To simplex with Ingrid, take out OASIS and Simplex mirrors (from USP tab on oasisgui),otherwise (simplexing with AG7) you need both mirrors in.

•Adjust the Simplex Iris so that the maximum intensity measured is between 10000 and 20000

•Click on Simplex

•Monitor the Merit Function (MF): image is considered good when MF < -0.015 (with AG7) or MF < -0.03 (with Ingrid)

•Usually image starts improving after 800-1000 cycles

•If after 2000 cycles MF doesn’t improve, stop simplex then start again: the algorithm may be stuck in a local minimum

•When the MF is satisfactory, stop simplex
