The calculation may take about 5 to 40 seconds. Do not refresh the page: output will appear at the bottom of the page (scroll down if necessary)

A message will be displayed if your job is waiting in the queue.

If it takes longer than 2 min, and you do not see an OUTPUT at the bottom of the page, please resubmit after 10min, as a possible crash would clear itself after 10minutes

If all of the above fails, contact the author to check for a possible crash or check for network failure

Option to Exclude Extended Objects:


For GUVcat cases only: exclude footprints of extended objects larger than arcmin

(see keywords INLARGEOBJ and LARGEOBJSIZE in GUVcat paper, Bianchi et al. 2017 ApJS 230, 24).
NOTE: given the current tessellation bin size of 6 arcmin for area calculations, this option is recommended only for LARGEOBJSIZE >> 6arcmin.

Select coordinate system and desired range: l,b or RA,Dec * required fields
