 Description   

As discussed on technical DRP 2d telecon, this ticket is to document creation of objects that would contain PSF instances across detector, which will be used as input for PIPE2D-347.

I am generating several spots for each fiber (as many as possible) and for each of these positions I am providing 100x100 numpy arrays which should be 5x times oversampled.

I plan to generate several models which correspond to different datasets/assumptions during modeling, so that we evaluate what works the best.

First examples placed in `/tigress/ncaplar/PIPE2D-450`.

positions_of_simulation_00 array contains positions of each PSF model. The columns are: 1. fiberId, 2. approximate x coordinate, 3. approximate y coordinate, 4. wavelength.

array_of_simulation_00 array contains arrays with 100x100 PSF models (5x times oversampled).

At the moment there are *_Aug05_v1 and *_Aug07_v1 versions, which correspond to different assumptions during creations of the final PSF.

These PSF are valid for F/2.8 data taken in May/June 2019, i.e., 17017 to 17646. It is not valid for Neon data from the same run (6238-16351)!!!

I plan to do the same analysis on the data taken in August, for which we should have all arc available. After that, there are many ways this can be improved....

Second set of examples placed in `/tigress/ncaplar/PIPE2D-450`. The description is same as before. The improvement is denser sampling of the imaging plane.

positions_of_simulation_00 array contains positions of each PSF model. The columns are: 1. fiberId, 2. approximate x coordinate, 3. approximate y coordinate, 4. wavelength.

array_of_simulation_00 array contains arrays with 100x100 PSF models (5x times oversampled).

At the moment there are *_Sep11_v1 and *_Sep12_v1 versions, which correspond to different assumptions during creations of the final PSF.

These PSF are valid for F/2.8 data taken in July 2019, i.e., runs 21400, 21604 and 21808.

(price) I have placed the *_Sep11_v2 and *_Sep12_v2 versions in `/tigress/ncaplar/PIPE2D-450` directory. These runs provide PSFs which are oversampled 10x times and are placed in the center of an image (see image centered_PSF_example.png), based on the discussion in PIPE2D-347.
