FWHM values of the profiles and were chosen to provide at least 0. As a result, when the band widths (full width at half maximum, FWHM) of the IPF and the spectral bands are roughly on the same order of magnitude, the measured band profiles exhibit a shape which is the convolution of Gaussian and Lorentzian functions, i. The characteristic depth dose deposition of ion beams, with a maximum at the end of their range (Bragg peak) allows for local treatment delivery, resulting in better sparing of the adjacent. The python directory contains the source code for a Python module for XrayDB. Shepherd1, R. Note that the angles with the optical axis of all the rays forming the rings are very small. The FWHM is as follows: FWHM= 2f p = 2FSR ˇ arcsin(1 r 1r 2 2 p r 1r 2) (4) From this de nition, the FWHM depends on the re ectivities and on the length of the cavity (via the Free-Spectral Range(FSR). measure_sharpness ([HDUlist_or_filename, ext]) Compute image sharpness, the sum of pixel squares. Python features a dynamic type system and automatic memory management. The installation will also automatically change FERRE's default filename-length from 120 to 180, to deal with the long filenames for the model libraries on the SDSS SAS (which is mirrored locally to use this code).
