NAME¶
pymoctool - manipulate Multi-Order Coverage maps
SYNOPSIS¶
pymoctool [INPUT] [COMMAND [FILE]] [--output OUTPUT]
DESCRIPTION¶
pymoctool can be used to manupulate Multi-Order Coverage (MOC) tools for the Virtual Observatory. It is a command-line tool and can handle files encoded as FITS, JSON, or ASCII. The tool maintains builds up a MOC stack using union, intersection and subtraction, with the pipeline processed in the order it is passed on the command-line.
Internally pymoctool uses and exposes the the PyMOC library found in the python-pymoc Debian package.
COMMANDS¶
- --catalog coords.txt [order NN] [radius NN]
- Render a circles using the flood-fill method on top of the MOC stack. The input text file should be whitespace records containing either RA+Dec pairs or Lat+Lon pairs.
- --help, -h
- Show top-level help
- --id
- Set new identifier for MOC stack
- --info, -i
- Display information about the MOC stack
- --intersection
- Intersect another MOC with the existing MOC stack
- --name
- Set new name for the MOC stack
- --normalize 0-29
- Set the maximum depth order of a MOC in the range 0-29
- --output, -o
- Output filename MOC
- --plot
- Project and render the MOC as a flattened all-sky map
- --subtract
- Subtract the a MOC from the existing MOC stack
- --version
- Show the backend PyMOC library version number
Detailed help for individuals commands can be found with pymoctool --help COMMAND
EXAMPLES¶
- pymoctool foo.fits --output foo.json bar.txt --output both.fits
- Load foo.fits then convert and the save a copy to foo.json perform a union merge with a text-format MOC called bar.txt and save the result both.fits
