stat_pt

ANSI-C program: stat_pt.c

NAME
stat_pt - calculate mean and sigma of float data (single record or all records)

SYNOPSIS
stat_pt <plist> <pmask> <pdata_in> <stat> [rec_num]

<plist>	(input) point list (int)
<pmask>	(input) point data stack of mask values (uchar, set to - to accept all points)
<pdata_in>	(input) point data stack (various types supported)
<stat>	(output) text file with layer, mean and sigma of point values
[rec_num]	record number in pdata_in to process (default -: all records)

EXAMPLE
stat_pt plist pmsk1 pres3 res3.stat -

determines the mean and standard deviation of each layer in the pres3 data statck

INSTALLATION
Source code stat_pt.c in ./IPTA/src, executable version stat_pt in ./IPTA/bin

DESCRIPTION
stat_pt is useful for determining the average and standard deviation of individual layers in a stack of residual phase values. All plints that have non-zero mask values are used in
the estimate. Either single layers or all layers can be processed. In this way the level of residual phase due to uncompensated atmosphere, deformation, or baseline error can be evaluated. Based on this evaluation some layers may be removed from consideration in developing the complete deformation model.

OPTIONS
none.
