COORDINATES tasks
The following tasks belong to the category COORDINATES:
``Coordinate transformations etc.''
In parentheses the name of the source file is given.
- ALLSKYPLOT
- Plot an all sky graticule in a given sky system
and plot shapes, markers and or images on that system.
(allskyplot.src)
- ASTROM
- Determine the sky-projection parameters CRVAL, CDELT,
CRPIX and CROTA
(astrom.c)
- COORDS
- Converts user supplied coordinates into physical coordinates.
(coords.c)
- DSSLOAD
- Loads a Digitized Sky Survey FITS file into a GIPSY set.
(dssload.c)
- FITSREPROJ
- This task if a versatile tool to re-project data in a FITS
file to another- or a modified world coordinate system.
The output can be converted to a GIPSY set or a
legacy GIPSY set (to be used for tasks like ROTCUR,
ROTMOD etc.).
(fitsreproj.src)
- MAPMAKER
- Plot set/subsets from a GIPSY set or slices from a FITS file
and annotate those plots with world coordinate labels and or
a graticule.
The program has a hard copy facility. It is ideal for comparing
channels in a radio data cube or for comparing different sources
(e.g. mixing GIPSY sets and FITS files). Put markers with keyword
MARKER= A marker will be plotted in all images, at least if its
position in world coordinates is part of the image.

- REGRID
- Create an output map with different grid along one axis.
(regrid.c)
- REPROJ
- Re-project a spatial map into another map with a different
coordinate system.

- SKYCALC
- Calculator for transformation of single positions between sky systems
(skycalc)
- SKYCALQ
- Calculator for transformation of single positions between
sky systems.
(skycalq.src)
- SKYTOOL
- Interactive coordinate transformation utility.
(skytool.c)
- SKYTRANS
- Transformation between equatorial, galactic, ecliptic and
supergalactic coordinates.
(skytrans.c)
- SLICE
- Make a slice through a set
(slice.c)
- VISIONS
- Display data from FITS files or
GIPSY sets. It allows for slices in any direction of the
data set. A plot can be made in several formats. A manual
is included in the program. Press f1 to get the handbook.
(visions.src)
- WCSFLUX
- Plot set/subsets from a GIPSY set or slices from a FITS file
and annotate those plots with world coordinate labels and or
a graticule. Then add shapes in one image. The shapes are copied
to other images using their world coordinates. Finally
calculate the flux in those shapes.
