Software and API.

smart Package#

smart.processing Module#

Functions#

`map_threshold`(im_map)	Set off disk pixels to black and clip the vmin and vmax of the map.
`calculate_cosine_correction`(im_map)	Find the cosine correction values for on-disk pixels.
`cosine_correct_data`(im_map[, cosmap])	Perform magnetic field cosine correction.
`smooth_los_threshold`(im_map[, thresh, ...])	We apply Smoothing, a noise Threshold, and an LOS correction, respectively, to the data.
`smart_prep`(im_map)	Prepare map for use in segmentation and characterization processes.

smart.differential_rotation Module#

Functions#

diff_rotation(ref_map, im_map)

Differentially rotate input map to reference map.

smart.indexed_grown_mask Module#

Functions#

`index_and_grow_mask`(current_map, rotated_map)	Performing Indexing and Growing of the Mask (hence the name IGM).
`plot_indexed_grown_mask`(current_map, ...[, ...])	Plotting the fully processed and segmented magnetogram with labels and AR contours optionally displayed.

smart.calculate_properties Module#

Functions#

`cosine_weighted_area_map`(im_map)	Calculate the cosine-weighted area map for a feature and determine the feature's total area.
`extract_features`(sorted_labels)	Extract binary masks for each feature found in index_and_grow_mask's sorted_labels.
`dB_dt`(current_map, previous_map)	A magnetogram differentially rotated to time 't' is subtracted from a processed magnetogram from time 't', and the resultant map is divided by their time separation, yielding a map of the temporal change in field strength.
`get_properties`(im_map, dB_dt, dt, sorted_labels)	Calculate various properties for each detected feature.

smart.polarity_separation_line Module#

Functions#

`separate_polarities`(im_map, feature_mask[, ...])	Divide detected feature into a positive and a negative mask, and dilate both masks.
`polarity_separation_line_length`(...)	Calculate the length of the polarity separation line (the boundary line between the positive and negative regions of an AR).
`get_strong_gradient_length`(im_map, ...[, ...])	Calculate the length of the strong gradients in the magnetic field.
