Input Fields

The following fields are available to provide input to the service (with some renderers, some of these fields may be unavailable):

NameTable Head DescriptionUnitUCD
freq Frequency range Frequency range in MHz N/A N/A
pos Position/Name SIMBAD/GLEAM-resolvable object (e.g. J013830-280538) or coordinates. Supporting formats: 1. dd, dd; 2. dd dd; 3. h:m:s, d:m:s; 4. h:m:s d:m:s; 5. h m s, d m s; 6. h m s d m s N/A N/A
proj_opt Projection ZEA = select a closest-match subset of the original mosaics, which are in Zenithal Equal Area projection; the regridding options will centre the mosaic on the selected location and use Montage to resample the mosaics to the desired projection N/A N/A
size Angular size Angular size of the cutout image in degrees. The maximum is 5 degrees, as the PSF changes on scales larger than this due to ionospheric and projection effects. N/A N/A

Default Output Fields

The following fields are contained in the output by default. More fields may be available for selection; these would be given below in the VOTable output fields.

NameTable Head DescriptionUnitUCD
accref Cutout FITS N/A N/A N/A
cr Cutout JPEG N/A N/A N/A
freq Frequency range Frequency range MHz N/A

VOTable Output Fields

The following fields are available in VOTable output. The verbosity level is a number intended to represent the relative importance of the field on a scale of 1 to 30. The services take a VERB argument. A field is included in the output if their verbosity level is less or equal VERB*10.
