Detailed Description

sfc.c contains the portion of libcpixe related to secondary fluorescence corrections.

This is still (in v1.0) under development so nothing is really used yet.

< < Todo: 135=9x15 (absorption lines x emission_lines). If more lines or absorptions are added, this should be raised. Note that a conditional compilation for the case in which M absorption lines are not used, could reduce it to 4x15 or even to 4x12 if M emission lines are neither considered. Only K and L absorption lines are considered (since M lines are hard to quantify anyway, we don't waste time). If SFC is desired for M lines too, change nabs to 9 here. Also, a conditional compilation could be implemented depending on a preproc variable called ,i.e., QUANTIFYMLINES In case M emission lines should not be considered for SFC, this for loop can be eliminated by a conditional compilation Definition at line 58 of file sfc.c.
