DUST Table Uploads

Overview:

The table upload feature reads coordinates and optional size parameter from an input table. Only the coordinate fields (either objname or ra, dec pair) are required; other parameters: csys, equinox, and size default to "EQU", "J2000", and "5.0 degrees". The name of your upload table can be typed in directly or selected using the [Browse...] button.

The input table file must be created on the client machine and the format is quite flexible. The following two paragraphs provide formatting guidelines and helps for ensure your table be successfully uploaded.

Most of IRSA's services allow users to enter single objects or coordinates into a web form, or they can upload a file containing multiple objects and coordinates. The latter method is called "Table Upload," for which IRSA accepts the following table formats:

There are two ways to ensure your tables will work with IRSA's services:

  1. Run your tables through IRSA's Table Reformat and Validation tool to identify possible errors.
  2. Read and follow the Using Tables With IRSA Services help document to learn and troubleshoot table formats, including:
    • Detailed descriptions of the four acceptable table formats
    • A description of how sexagesimal and Galactic coordinates are handled by IRSA services
    • Best practices for creating tables
    • Troubleshooting solutions for common error messages

Input Parameters

  • "objname"

    The objname can be any name resolvable by NED or SIMBAD. The coordinate information is required, but it could be either the "objname" or the "ra" and "dec" fields; if it both are present, "ra" and "dec" override the "objname".

  • "ra", "dec", "csys", "equinox"

    These four fields make up the object string to be parsed by IRSA's lookup service. "ra" and "dec" can be specified either in degrees or in sexigesimal; if "csys" and "equinox" are not specified, they default to "equ" and "j2000". The acceptable "csys" values are "equ", "ecl", "gal", and "sgal". The acceptable "equinox" values are "j2000", "b1950". "ra" and "dec" are required only if objname is not present.

  • "size"

    This is a double precision number specifying the size of the image cutout in degrees. This field is optional; it defaults to 5.0 degrees.
