The BigFoot code

The questions posed by the discovery of the cosmic acceleration inspired a number of ambitious ground-based and space-based projects, making this early 21st particularly exciting for cosmology.

The ''footprint'' is the patch of the sky scanned by a given galaxy survey. In order to help astronomers simultaneously visualise footprints of multiple surveys, Alex Merson and myself have designed a tool called BigFoot. An example is shown in the Figure below.
