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.

Here is the call graph for this function:

int inrange	(	double	value,
		double	min,
		double	max
	)

Checks if a value is within limits

Parameters:

	value	(I) Value to check
	min	(I) minimum limit
	max	(I) maximum limit

Returns:

1 if value is inside range, 0 otherwise

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.

<

Todo:

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

Todo:

In case M emission lines should not be considered for SFC, this for loop can be eliminated by a conditional compilation
