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 headers. 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
