plot and calculate parameters of a reflectivity curve
SYNOPSIS¶
rcpeak [options] filename1 filename2 ... filenameN
DESCRIPTION¶
A program to plot and calculate parameters of a reflectivity curve or any kind of distribution with a single peak
OPTIONS¶
For a brief summary run:
rcpeak -h
| -v, --version: | show version of program. |
|---|---|
| -h, --help: | show summary of options. |
| -o F, --output=F: | |
| write results to file F (default to stdout) | |
| -p, --plot: | plot fitted model distributions (Gaussian and Lorentzian) |
| -c, --contrast: | calculate spectral contrast at 1.578*FWHM |
| -u unit, --unit=unit: | |
| conversion factor for x-axis | |
| -m mult, --mult=mult: | |
| multiplication factor for y-axis | |
| -x Nx, --name_x=Nx: | |
| x-axis label/unit | |
| -y Ny, --name_y=Ny: | |
| y-axis label/unit | |
| -b bkg, --bkg=bkg: | |
| user defined background for calculation of FWHM (by default determined from the peak tails) | |
| -t n_th, --th=n_th: | |
| x-values (e.g., rocking curve angle th) are in column number n_th (default n_th=1) | |
| -r n_r, --r=n_r: | |
| y-values (e.g., reflectivity values r) are in column number n_r (default n_r=2) | |
| -d nder, --deriv=nder: | |
| perform interpolation with number of points, calculate and plot numerical derivative of data (e.g., for beam size estimation in a knife-edge scan) | |
| -n, --normalize: | |
| normalize data for plotting (e.g., userful for visual comparision of FWHM of peaks with different maximum intensity) | |
