Computes antenna surface RMS before and after panel surface fitting Returns: RMS before panel fitting OR RMS before and after panel fitting

fit_surface()

Loops over the panels to fit the panel surfaces

correct_surface()

Apply corrections determined by the panel surface fitting methods to the antenna surface

print_misc()

Print miscelaneous information on the panels in the antenna surface

plot_mask(basename, caller, parm_dict)

Plot mask used in the selection of points to be fitted :param basename: basename for the plot, the prefix ‘ancillary_mask’ will be added to it :param caller: Which mds called this plotting function :param parm_dict: dictionary with plotting parameters

plot_amplitude(basename, caller, parm_dict)

Plot Amplitude map :param basename: basename for the plot, the prefix ‘ancillary_amplitude’ will be added to it :param caller: Which mds called this plotting function :param parm_dict: dictionary with plotting parameters

plot_phase(basename, caller, parm_dict)

Plot phase map(s) :param basename: basename for the plot(s), the prefix ‘phase_{original|corrections|residuals}’ will be added to

it/them

Parameters:

• caller – Which mds called this plotting function

• parm_dict – dictionary with plotting parameters

plot_deviation(basename, caller, parm_dict)

Plot deviation map(s) :param basename: basename for the plot(s), the prefix ‘deviation_{original|corrections|residuals}’ will be added

to it/them

Parameters:

• caller – Which mds called this plotting function

• parm_dict – dictionary with plotting parameters

plot_screw_adjustments(filename, parm_dict)

Plot screw adjustments as circles over a blank canvas with the panel layout :param filename: Name of the output filename for the plot :param parm_dict: Dictionary with plotting parameters

export_screws(filename, unit='mm', comment_char='#')

Export screw adjustments for all panels onto an ASCII file :param filename: ASCII file name/path :param unit: unit for panel screw adjustments [‘mm’,’miliinches’] :param comment_char: Character used for comments

export_xds()

Export all the data to Xarray dataset :returns: XarrayDataSet containing all the relevant information

export_to_fits(basename)

Data to export: Amplitude, mask, phase, phase_corrections, phase_residuals, deviations, deviation_corrections,

deviation_residuals

conveniently all data are on the same grid! Returns:
