Routines for calculating standing wave x-ray fluorescence and x-ray reflectivity

Project description

pySWXF

Code for calculating reflectivity and standing wave x-ray reflectivity

refl_funs Routines to calculate specular reflectivity

* mlayer_rough:		Calculates reflectivity from a multilayer substrate.  Approximates roughness as gaussian
* mlayer_conv		Convolutes mlayer_rough with a gaussian resolution function
* reflection_matrix 	returns reflection and transmission data from multilayer array.  Uses mlayer_rough
* eden_to_rho		converts between electron density and mass density
* rho_to_n		converts between mass density and index of refraction
* rho_to_rhoe		converts between mass density and electron density

spec_utils Routines to read data from spec files

* readscan		read a data scan
* readmcascan		read a data scan where mca data saved to spec file 
* merge_scans		combine spec scans from a sequence
* merge_duplicates	take combined scans and average points at same location
* getscan			uses readscan to specifically read theta two-theta data
* getscan_bg		reads a scan and two backgrounds and returns background subtracted data
* list_scans		lists scans in spec file
* dt_correct:		corrects MCA dead time from CLS mca
* get_mca_data_CLS: 	reads MCA data from Canadian Light Source Brockhouse Beamline
* get_mca_data_DND:	reads MCA data from DND cat
* plot_mca_sum:		Sums all mca data from a scan and plots intensity vs energy 
* peak_label:		Plots a label for a peak on an MCA plot
* K_label:		Labels all K-lines from an element
* L_label:		Labels all L-lines from an element
* get_br_amps		Fits bromine peak to gaussian and nearby gold peak.  Returns only Br amplitude
* plot_br_fluor		Fits all bromine amplitudes from scan and returns plot of intensity vs. angle
* get_edge_absorb		Finds the absorbtion probability of an edge by brute force (e.g. 
				calculates values on either side of edge and subtracts
* Au_L_peak:		Simulates intensity from Au L peaks.  Input to get_br_amps
* Br_K_peak:		Simulates intensity from Br K peak.  Input to get_br_amps
* Br_peak_sim:		Combines Br and Au peaks into total intensity.  Input to get_br_amps
* cbwe: combine two sets of data with error bars
* cbwe_s: same as cbwe but for two scalers rather than two vector
* get_mca_data_CLS_Nov: reads mca data from file for format from November 2023
* get_fluor_data:	reads mca data using get_mca_data_CLS_Nov and combines with related spec data
* fit_fluor_data:	fits bromine peak amplitudes using model specified in peak_model
* get_reflectivity_CLS(fname, datadir, scan):
* get_refl_sequence_CLS(fname, datadir, firstscan):
* plot_refl_sequence_CLS(fname, datadir, firstscan):

fluor_fit Routines to fit fluorescence curves

* make_bilayer_model: models bilayer to go on top of multilayer
* sample_sim: takes parameters and makes a layer stack for sample 
* multilayer_ref_Ti calculates reflectivity from old multilayer
* multilayer_fluor: calculates fluorescence from old multilayer 
* sample_sim_new: creates sample stack for new multilayer 
* multilayer_ref_new calculates reflectivity from new multilayer o
* multilayer_ref_new_model: fitting model for new multilayer
* multilayer_model_Ti: fitting model for old multilayer

Some of these are still a work in progress, proceed with caution
