Image Cutout Access Methods

Single-Image Cutout Download

This form can be used to request a single cutout from the survey. Please change the default values to specify the cutout region.

RA: DEC:
Coordinates: Filter:
Image Size: Pixels Arcminutes

Multi-Image Cutout Download

This form can be used to upload a regions file to the server to request multiple cutouts. The format of the file is described in the cutout task help page, but briefly, each region requested should contain at least an RA (in hours) and DEC (in degrees) center position, one position per line in the file. Each line may additionally contain an ra and dec width (in pixels if specified with a trailing 'p', otherwise assumed to be arcminutes), the coordinate system used, and a comma-delimited list of filters to extract. Values not specified in the regions file will be derived from the form settings. Results are returned as a gzip-compressed tarfile of the resulting FITS images (Note: the file has a ".tgz" extension).

Multi-Image Cutout Viewer

This form can be used to request a cutout from the survey to display the science data in the requested filters at the given position. An RGB composite image (where the 'R' band is the 'I' filter, the 'G' band is the 'R' filter, and the 'B' band is the 'Bw' filter) will also be created if all three filters are selected. Values may be changed or the cutouts can be downloaded in the resulting form.
