filter_mesh_parameters#

aiapy.psf.filter_mesh_parameters(use_preflightcore=False)[source]#

Geometric parameters for meshes in AIA filters used to calculate the point spread function.

Parameters:

use_preflightcore (bool, optional) – If True, use the pre-flight values for the filter mesh parameters

Returns:

meshinfo – Dictionary with filter mesh information for each channel. Each channel entry then contains another dictionary with the following keys describing filter mesh properties of that channel (see Table 2 of [1]):

angle_arm: Angles of the four entrance filter arms
error_angle_arm: Error in angle of the four entrance filter arms
spacing_e: Distance between diffraction spikes from entrance filter
spacing_fp: Distance between diffraction spikes from focal plane filter
mesh_pitch: Pitch of the mesh
mesh_width: Width of the mesh
width: Width applied to the Gaussian such that after convolution we have the proper width (\(4/3\) at \(1/e\) of max)

Return type:

dict
