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)
Program to copy set and subsets. It can also increase or
decrease the frame size of the subsets. BLANKs will be
written in the output set outside the original subset frame.
(copy.shl)
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)
Create an output set with profiles extracted from an
input set at positions in subsets that are either
1) defined by ellipses, 2) entered manually or
3) entered with the graphics cursor.
(ellprof.c)
Adds the keywords OBS and SCANTYPE to the header
if these are not present. This is neccessairy since
these keywords have lately been added to the
standard keyword-list at snip level and IRDS_EXTEND
and IRDS_ENQUIRE_SNIP have been adapted to this.
(fixsnip.c)
General macro based plot program for interactive use
of PGPLOT subroutines and the Gipsy Data Subsystem (GDS).
See also:The GIPSY Recipes Book . (gplot.c)
Program to insert (multiple) (parts of) a set into another
existing set.
(insert.shl)
INSPECTOR writes slices through a 3d GIPSY data cube.
It overlays radial HI velocities (i.e. 'tilted ring'
circular velocities) on velocities in XV diagrams and
lets you adjust the tilted ring parameters to get a
better fit.
See also:INSPECTOR Supplementary documentation. (inspector.src)
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)
Solves the radial surface density distribution from a strip
integral of the brightness distribution. USE PROGRAM
RADIAL AS FRONT END FOR RADPROF.
(radprof.shl)
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)
This program calculates the rotation curve for a truncated
exponential disk (Casertano, M.N.R.A.S., vol. 203,
p735-p747, 1983), or for any other user supplied density
law. It can also calculate the rotation curve for a
spherical bulge.
(rotmod.c)
XGAUFIT estimates parameters for multi component one
dimensional gauss functions using data in selected
profiles. It can use these estimates to fit the
parameters to the data in a least squares fit.
Output is send to subsets in a set.
