The columns are: 1. fiberId, 2. approximate x coordinate, 3. approximate y coordinate, 4. wavelength.</p> <p>array_of_simulation_00 array contains arrays with 189x189 PSF models (9x times oversampled).</p> <p>At the moment there is *_Jan08_v2 versions available. </p> <p>Compilations of figures:</p> <p>1. Median_wavefront - showing summary of wavefront measurments<br/> 2. quality_in_focus and quality_in_defocus - showing chi^2 after subtraction of model, as a function of variable chi2_max (chi^2 without any subtraction).</p> <p>3. p4_z5,p1_z5,0_z5,m1_z5,m4_z5  - showing as an example how Z5 is changing as defocus<br/> 4. example_2d and example_1d - showing an example of the model and subtraction in 2d and 1d for a single spot; showing two example with lower and higher flux</p> <p>There is an obvious problem in size of the psf at higher flux, visible as the ring around the psf solution. I will open a ticket to tackle this problem.</p> <p> </p> <p>Observing Figure quality_in_focus once can observe how point of Argon at around log10(chi^2_max)=2.7 &amp; log10(chi^2)=1 perform particularly poorly. I see that all of these points are from redest available Argon point, at 966.06 nm. It seems that there is some sort of continuum at these locations which is not accounted for when cutting the images.</p> Blocks PIPE2D-721 Relates PIPE2D-696 PIPE2D-700 PIPE2D-614 PIPE2D-654 PIPE2D-701 PIPE2D-490 PIPE2D-670 Development Rank 0|02qpq3:r1a Sprint 2DDRP-2021 A Story Points 6.0
