Ginga Specific Software: Program CORRAC
Program corrac performs various types of correlation
analysis (Spearman's, Pearson's and sum square difference of ranks')
on Ginga housekeeping (HK) data. Algorithims are taken from
Numerical Recipes' subroutines Spear and Pearsn.
A Ginga CUBE or TIME series containing HK
parameters. However, the program will also work with any HDS file
containing two one-dimensional arrays of equal size, providing it also
contains an array NELS(3) (where NELS(1) is equal to the
size of the one-dimensional arrays).
Corrac requires four input parameters. The QX parameter
system is used to read the parameters.
| CAC_DATIN | The name of the input CUBE
or TIME series. |
|
| | CAC_YNAM1 | The name of the array
containing the dependant variable. |
|
| | CAC_XNAM1 | The name of the array
containing the other variable. |
|
| | CAC_IGNORE | If any of the data values
in X or Y equal IGNORE then this point is omitted from the
regression. |
