IRAF Help package for grasp.velcal:
gencal - generates synthetic calibration
image from polynomial coefficients (used in self-test)
getcal - calculates the wide-band and
narrow-band correction images from input east and west calibration
images and phase angle and balance angle information
iii - transforms phase velocity, modulation
amplitude, and mean intensity into three-phase intensity images
mag - Calculate magnetogram
nbcalc - calculates narrow-band correction
image
plr2rec - transforms vector from polar
(velocity,modulation) into rectangular coordinates
rec2plr - transforms from rectangular
coordinates into polar
sdtst - calculates the standard deviation
of an image using a template
tstim - self-test for VELCAL package
ucor - transforms
three- or six-phase intensity images into phase velocity, modulation amplitude,
magnetogram, and mean intensity and corrects the oscillation velocity, modulation
amplitude and magnetogram for wide- and narrow-band effects and
scales the velocity to m/s
vcor - transforms three-phase intensity
images into phase velocity, modulation amplitude, and mean intensity
then corrects oscillation velocity for wide- and narrow-band
effects and does laser calibration
vlascor - calibrates oscillation phase
velocity with laser phase
vmi - transforms three-phase intensity
images into phase velocity, modulation amplitude, and mean intensity
vmi2pmi - converts velocity, modulation,
intensity into phase velocity, modulation, intensity
wlmcalc - calculates spurious modulation
(i.e. wide-band) correction image
wlmcor - corrects oscillation image
for spurious (i.e. wide-band) effects
