Overview
mDAG creates an XML-based Directed Acyclic Graph (DAG) that specifies "jobs" or Montage modules to be run to produce a mosaic, "files" to be consumed or generated during processing (input, intermediate, and output files), and "dependencies" between jobs and files that imply an order in which jobs should be run. In this "abstract graph", logical names are assigned to jobs and files. The abstract graph is intended to be an input to a job scheduler, such as Pegasus in the Chimera Virtual Data System.
Options
-
-h -
Output mosaic is based on a header file rather than explicit object name (for location), sizes and scale.
Arguments
- survey
-
mDAG has custom code for dealing with surveys (e.g. DSS) where we know we have to use the slower mProject module rather than mProjectPP.
- band
-
mDAG also has custom code for the 2MASS survey where Montage scales the data to a project-specified magnitude zero point by band (J,H,K).
- objstr
-
Object name, resolved through NED/SIMBAD for sky location.
- width/height
-
Size of the image in degrees.
- cdelt
-
Pixel scale in degrees.
- hdrfile
-
Instead of objstr, width, height, and cdelt the user an provide a pre-built FITS header.
- workdir
-
There are a collection of files the processing will need ane which mDAG creates. The user needs to create a location for this and give it to mDAG.
- workurlbase
-
While working, some files in the workspace are accessed via URL. Again, this needs to be set up by the user beforehand.
- urlbase
-
Optionally, results can be made URL-accessible if this parameter is given.
Result
If successful, the workspace will be populated with severeal tables and with the "dag.xml" file to be given to the workflow manager.
