# Data files descriptions
Most of the files contained in this folder are intermediate results that I later used for plotting a figure or - in some cases - continuing an analysis.
## `/ADC rotation`
Contains the "nominal" and "perturbed" geometric distortion points for various rotation angles of the ADC.
**Filename structure**
Example: `GD_obscured_PSF_xcentroid_expected_zern_psd_rot0.001.pkl`
Total 84 files.
* `GD` = Geometric distortions
* `obscured_PSF` = Obscured pupil function used for the ELT pupil, which also means that an obscured Airy pattern was fitted to find the centroid location.
* `xcentroid_expected` = "Nominal" or unperturbed x-coordinates of the PSF on the image plane for the 11x11 grid of field points.
* `ycentroid_expected` = "Nominal" or unperturbed x-coordinates of the PSF on the image plane for the 11x11 grid of field points.
* `xcentroid_found` = Perturbed (with a WFE on the ADC prisms) x-coordinates of the PSF on the image plane for the 11x11 grid of field points.
* `ycentroid_found` = Perturbed (with a WFE on the ADC prisms) y-coordinates of the PSF on the image plane for the 11x11 grid of field points.
* `zern_psd` = Type of PSD that was applied for this particular simulation iteration. Here a combination of both a zerike polynomial component as well as a PSD component.
* `rotx.xx` = Rotation of x.xx degrees of the ADC prisms for this result.
## `/compressed items`
Contains various larger files with the used wavefront errors and an input field distribution which would speed things up during the analysis.
* `ADC_input_field_1001x1001_1.49_onaxis_circular.pkl` = The nominal complex field distribution at the start of the ADC. Useful for quick iterative development of the code. Assumes a circular aperture.
* `ADC_input_field_1001x1001_1.49_onaxis_obscured.pkl` = The nominal complex field distribution at the start of the ADC. Useful for quick iterative development of the code. Assumes an obscured circular aperture.
* `ADC_input_field_1001x1001_1.49_onaxis.pkl` = The nominal complex field distribution at the start of the ADC. Useful for quick iterative development of the code. Assumes the segmented ELT pupil.
**Wavefront error file structure**
Example: `ADC_tWFE_p1_psd_25nm.pkl`
* `ADC` Component for which the WFE is designed.
* `tWFE` Transmitted wavefront error.
* `px` The wavefront error is to be applied to prism x of the ADC.
* `psd_xxnm` Definition used for generating the WFE, with xx nm of RMS. Can also appear combined with lower order zernike modes as `zern_xxnm_psd_xxnm.pkl`
## `/GD Focal Plane WFEs`
Contains the "nominal" and "perturbed" geometric distortion points when a phase perturbation is added to the intermediate (ELT) focal plane.
**Filename structure**
Example: `GD_IFP_zoom2_obscured_PSF_ycentroid_expected_zern_psd.pkl`
Total 98 files, of which 96 GD coordinates.
* `GD` = Geometric distortions
* `IFP` = Intermediate Focal Plane - The geometric distortions are still in the final MICADO image plane.
* `zoomx` = Denotes that only a part of the full MICADO field of view is analysed. See list below.
* `obscured_PSF` = Obscured pupil function used for the ELT pupil, which also means that an obscured Airy pattern was fitted to find the centroid location.
* `xcentroid_expected` = "Nominal" or unperturbed x-coordinates of the PSF on the image plane for the 11x11 grid of field points.
* `ycentroid_expected` = "Nominal" or unperturbed x-coordinates of the PSF on the image plane for the 11x11 grid of field points.
* `xcentroid_found` = Perturbed (with a WFE on the ADC prisms) x-coordinates of the PSF on the image plane for the 11x11 grid of field points.
* `ycentroid_found` = Perturbed (with a WFE on the ADC prisms) y-coordinates of the PSF on the image plane for the 11x11 grid of field points.
* `zern_psd` = Type of PSD that was applied for this particular simulation iteration. Here a combination of both a zerike polynomial component as well as a PSD component. Note: actually only PSD curves where used in this particular analysis. But the name was not changed.
**Description of zoom parameter**
In the list below the normalised field coordinates correspond to -1:1, this is from -7.5e-3 to +7.5e-3 degrees or around 27 arcseconds.

## `/GD full field`
