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)
