Surface Photometry

The VISTA commands for surface photometry of extended objects are:

CUT
extract a brightness profile cut along any position angle
PROFILE
compute surface brightness profile by elliptical isophote fitting
ANNULUS
compute a radial profile by azimuthal averaging
RECON
reconstruct an image from a surface photometry profile
APER
aperture photometry of an extended object
ROUND
deproject spirals or elliptical images
POLAR
regrid an image into polar coordinates
EGAL
reconstruct a galaxy from its profile
SNUC
surface photometry of multiple galaxy systems
RENUC
reconstruct galaxies from multiple galaxy photometry
SECTOR
surface photometry of star clusters or complex objects
AEDIT
edit values in selected image regions
CLPROF
clear the contents of the profile common block
CPROF
correct the results of a profile calculation
EMAG
aperture photometry with elliptical apertures
EMARK
interactively specify ellipse parameters for EMAG
RMARK
interactively set maximum radius for EMAG
ELLMAG
compute elliptical magnitudes for PROFILE ellipses
TVPROF
display PROFILE results on the image display
OPREP
open a batch surface photometry preparation file
CLPREP
close a batch surface photometry preparation file
RPREP
