PROGRAM:

NAME


mDAG - Create a Directed Acyclic Graph (DAG) for Pegasus

SYNOPSIS


mDAG survey band objstr width height cdelt
workdir workurlbase [urlbase]

mDAG -h survey band hdrfile workdir workurlbase [urlbase]

DESCRIPTION


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.
