dabam: (dataBase for metrology)

python module for processing remote files containing the results of metrology measurements on X-ray mirrors

classes:

• dabam

main functions:

• cdf (calculate antiderivative function)

• psd (calculate power spectral density)

• write_shadowSurface (writes file with a mesh for SHADOW)

• func_ellipse_slopes evaluates the ellipse slopes profile equation

MODIFICATION HISTORY:

• 20151103 srio@esrf.eu, restructured to OO

• 20151118 srio@esrf.eu, cleaned and tested

• 20190731 srio@lbl.gov, updated version, allows reading external files, change server, etc.

Functions

autocorrelationfunction(x1, f1)	A function that calculates the autocovariance function and correlation length of a 1-d profile f(x).
cdf(sy, sz[, method])	A function that calculates the profile from the slope by simple integration (antiderivative)
dabam_summary([nmax, latex])	creates a text with the summary of all dabam entries.
dabam_summary_dictionary([surface, ...])	Obsolete.
func_ellipse_slopes(x, p, q, theta, shift)	A function that calculates the derivative (y'(x) i.e., slopes) of a ellipse y(x) defined by its distance to focii (p,q) and grazing angle theta at coordinate x=0
main()	Main program to run dabam from command line.
make_json_summary([nmax, ...])	Obsolete.
moment(array[, substract_one_in_variance_n])	Calculate the first four statistical moments of a 1D array.
psd(xx, yy[, onlyrange])	A function that calculates the PSD (power spectral density) from a profile.
write_shadowSurface(s, xx, yy[, outFile])	A function that writes a mesh surface in SHADOW format.
