F5¶

class mmtwfs.wfs.F5(config={}, plot=True)[source] [edit on github]¶

Defines configuration and methods specific to the F/5 WFS systems

Methods Summary

`calculate_recenter`(fit_results[, defoc])	Perform zero-coma hexapod tilts to align the pupil center to the center-of-rotation.
`focal_plane_position`(hdr)	Need to fill this in for the hecto f/5 WFS system.
`process_image`(fitsfile)	Process the image to make it suitable for accurate wavefront analysis.
`ref_pupil_location`(mode[, hdr])	For now we set the F/5 wfs center by hand based on engineering data.
`reference_aberrations`(mode[, hdr])	Create reference ZernikeVector for 'mode'.

Methods Documentation

calculate_recenter(fit_results, defoc=1.0)[source] [edit on github]¶: Perform zero-coma hexapod tilts to align the pupil center to the center-of-rotation. The location of the CoR is configured to be at self.cor_coords.

focal_plane_position(hdr)[source] [edit on github]¶: Need to fill this in for the hecto f/5 WFS system. For now will assume it’s always on-axis.

process_image(fitsfile)[source] [edit on github]¶: Process the image to make it suitable for accurate wavefront analysis. Steps include nuking cosmic rays, subtracting background, handling overscan regions, etc.

ref_pupil_location(mode, hdr=None)[source] [edit on github]¶: For now we set the F/5 wfs center by hand based on engineering data. Should determine this more carefully.

reference_aberrations(mode, hdr=None)[source] [edit on github]¶: Create reference ZernikeVector for ‘mode’. Pass ‘hdr’ to self.focal_plane_position() to get position of the WFS when the data was acquired.
