UTILITY tasks

CALC

Calculate expressions (using variables) and exercise GIPSY input syntax (calc.c)

CBLANK

Converts datavalues to BLANK and vice versa. CBLANK also checks whether the data are legal (i.e. it checks for NaN's etc. and replaces them by BLANKS). (cblank.shl)

CODER

Create C-code for simple programs (coder.c)

COLA

Control language for use with Hermes. (cola.c)

CREATE

Creates a SET (and subsets) (create.shl)

CURSOR

Write positions (GRIDS and PHYSICAL coordinates), pointed with an interactive graphics cursor in a GIDS overlay, to screen or ASCII file. Write also (interpolated) image values. (cursor.c)

DELETE

Delete sets (delete.c)

DISK

DISK lists the contents of the current directory and lists some properties of GIPSY sets. (disk.c)

DSSLOAD

Loads a Digitized Sky Survey FITS file into a GIPSY set. (dssload.c)

EXTEND

Copy set and extend new set with one or more axes. Change size of set. (extend.c)

FIT

Fit a set of data points (Xi,Yi) to a model, that depends nonlinearly on its parameters, using a Chi-squared minimization. (fit.c)

FIXHED

Add, change, delete or list item(s) in set header (fixhed.c)

FUNPLOT

Interactive function plotting utility. (funplot.src)

GDS2TEXT

Put GDS image data in ASCII file and vv. Use a format for the numbers. Add (physical coordinates) to the data if in 'export' mode. (gds2text.c)

GETVAL

Get image values at given positions in a set (getval.c)

HEADER

Display header information (header.c)

HELP

Display purpose lines or categories or complete documentation of tasks (subroutines and general items). Data can be directed to printer also. (help.c)

HISTORY

read, or update history or comment in set header (history.c)

inidisplay

Initializes the display for GIPSY applications. (inidisplay.c)

lfits

List FITS files on a tape (lfits.c)

MINBOX

MINBOX calculates the smallest box in a (sub)set, outside which only blanks exist and creates an output set with the calculated box size. It stores the box in physical coordinates in the header of the set. (minbox.c)

MTCOPY

Copies selected files from one tape device to another tape device. Tape device can be a real tape unit or a directory on disk. (mtcopy.c)

MTLIST

Lists files on a tape device. (mtlist.c)

NEWS

Displays the GIPSY news items. (news.c)

PLOTSYM

Plot PGPLOT's marker- and Hershey symbols (plotsym.c)

pplot.c

Plot the intensity along a line through a set. (pplot.c)

PRINT

print part of a (sub)set on terminal/printer. (print.c)

RANDOM

Generate random numbers from various distributions. Add noise to sets. Write random numbers to an (ascii) file on disk. (random.c)

RECOVER

Recover a corrupt GDS set (recover.f)

REGRID

Create an output map with different grid along one axis. (regrid.c)

RENAME

Renames a GDS set. (rename.c)

RENZOGRAM

Build and execute a GPLOT input file that plots contours per level for different subsets. The contours can be an overlay on a set. (renzogram.c)

report

reports ( the fix of ) a bug or a wish (report.c)

REWIND

Rewinds a tape. (rewind.c)

RFITS

Load FITS files from tape into a GIPSY set. (rfits.c)

RHEAD

list header elements ( descriptors ) and their level in grids (rhead.shl)

SCALE

Program to scale the data in subsets by a factor and an offset. (scale.shl)

SKIP

Skips files forward or backward on tape. (skip.c)

SKYTOOL

Interactive coordinate transformation utility. (skytool.c)

SKYTRANS

Transformation between equatorial, galactic, ecliptic and supergalactic coordinates. (skytrans.c)

.....

Replace values by a box with other values e.g. for removing a bad perimeter of an velocity field. (snapper.c)

TABLE

GIPSY Table maintenance program (table.c)

TRANSFORM

Transform a (sub)set using rotation, scaling, translation etc. (transform.c)

WFITS

Writes disk set and subsets onto magnetic tape (or disk) in FITS format. (wfits.c)
