CALCULATION tasks

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)
