CALCULATION tasks


The following tasks belong to the category CALCULATION:
``Calculations with set data'' In parentheses the name of the source file is given.
CALC
Calculate expressions (using variables) and exercise GIPSY input syntax (calc.c)
COMBIN
Combine sets to create new sets using mathematical expressions. (combin.shl)
CORMAP
Check whether there is a correlation between two maps (cormap.c)
DECIM
Decrease size of a set in any direction with an integer factor (decim.c)
FLAT
Apply a flat field correction to a map by fitting a 2-D polynomial to the background. (flat.c)
FLUX
Program to calculate flux in user defined box. (flux.c)
GRADIENT
Calculates the gradients or the laplacian of a map, using three by three sized templates. (gradient.c)
MEAN
Program to calculate the mean of a number of subsets. (mean.shl)
MEDIAN
Calculate median of data from set, file, table or expression. (median.c)
MFILTER
Apply a median (or average) filter to a (sub)set (mfilter.c)
MNMX
This program finds the minimum and maximum value in a subset or part of a subset. It also counts the number of blanks. (mnmx.shl)
MOMENTS
Program to calculate moments and other properties of a profile (moments.c)
PATCH
Find data values at positions of blanks interpolating the data in a small volume around the blanks. (PATCH)
reswri
RESWRI derives the kinematical parameters from the observed velocity field by fitting tilted-rings to the velocity field and fits harmonic terms after convergence of the ROTCUR part of code. RESWRI uses the 1 sigma error-field to calculate its errors. (reswri.c)
ROTCUR
ROTCUR derives the kinematical parameters from the observed velocity field by fitting tilted-rings to the velocity field. (rotcur.c)
STAT
Program to calculate elementary statistics in user (stat.c)
SUM
Program to add a number of subsets. (mean.shl)
