Code for calculating reflectivity and standing wave x-ray reflectivity

Modules

MCA_utils Routines for getting an manipulating MCA data 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 Routine to combine data with error bars cbwe: combine two sets of data with error bars cbwe_s: same as cbwe but for two scalers rather than two vectors

get_prof Routine to get electron density profile from list of amplitudes centers and roughnesses get_prof: Gets profile get_dprof: Gets profile derivative get_realspace Routine to get realspace profile for bilayer. Probably obselete get_realspace half routine to do a 1/2 boxcar average of data set and halve length of dataset half 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 refraction_funs Routines to calculate indices of refraction for various elements. Probably could be replace by just using equivalent from xraydb n_elem Index of refraction of an element n_water Index of refraction of water n_SiO2 Index of refraction of Silica 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

standing_wave Routines to calculate x-ray standing wave properties 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

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