Name
imsize - Print size of image in WCS and pixels
Synopsis
imsize [-vcd] [-p scale] [-b ra dec] [-j ra dec] FITS or IRAF file(s)
Description
imsize is a utility for printing the region covered by an image using the world coordinate system parameters in IRAF and FITS image head-
ers. It converts IRAF .imh image headers to a FITS format before extracting the information. For IRAF files, the image dimensions and the
object name are set from the binary portion of the header.
Options
-b [<RA> <Dec>]
Output B1950 (B1950) coordinates (optional center)
-c Format output without pixel dimensions (optional size change)
-d Format output as input to DSS getimage (optional size change)
-e Add epoch of image to output line
-j [<RA> <Dec>]
Output J2000 (J2000) coordinates (optional center)
-n <number>
Number of decimal places in output (default 3)
-p <scale>
Initial plate scale in arcsec per pixel (default 0)
-r Print range in RA and Dec
-v Print more intermediate information for debugging
-z Use AIPS classic projections instead of WCSLIB
