CORREL-Correlate two or three data sets.

Usage:

correl inlist out logfil

Description:

This routine correlates two or three data sets. Either pair is subjected to a linear fit and the third data set is subjected to a two-parameter linear fit (i.e. regarded as a linear function of the first and second data sets). Each data set may be an NDF section. All must have the same dimensions.

Parameters:

INFO

INFO = _LOGICAL (Read) If false, the routine will issue only error messages and no informational messages. [YES]

VARUSE

VARUSE = _LOGICAL (Read) If false, input variances are ignored. [YES]

INLIST

INLIST = LITERAL (Read) The group of input NDFs. Two or three NDFs must be specified. A complicated INLIST could look something like

M_51(25:35,-23.0,-24.0),M101,^LISTFILE.LIS

This example NDF group specification consists of - one identified NDF from which a subset is to be taken, - one identified NDF, - an indirection to an ASCII file containing more NDF group specifications. That file may have comment lines and in-line comments, which are recognised as beginning with a hash (#).

OUT

OUT = FILENAME (Read) The ASCII output file where the data points are written into a table. A new file will be opened. No file will be opened, if "!" is entered. The table in OUT is without any information else than the values from the 1st, 2nd, 3rd data array and errors from the 1st, 2nd, 3rd variance array in that order. [!]

LOGFIL

LOGFIL = FILENAME (Read) The ASCII log file where fit results are written to. This will be opened for append, if such a file exists.
