“Sky Coverage”
•" Refers to the task of determining what WISE
pointed towards during the course of the survey.
•" What is the total sky coverage of the PR?
–" 41,252.916 square degrees uniquely contained in the
18,240 Atlas Tiles = 100.000%
–" More like 44,620.36 square degrees non-unique
–" Valid pixels: Band Square Degrees % of Sky % Valid

Things to Understand
•" Coverage (and hence sensitivity) varies over sky because
of survey strategy
•" Holes in All-Sky Release Atlas Tile coverage:
–" Due to torque rod gashes
–" Where there’s severe scattered moonlight
–" At saturated regions
•" Atlas and Catalog coverage intentionally attenuated in 41
Tiles near Ecliptic poles (full-depth coadds exist, but
source extraction left to the user)
•" Catalog source density suppressed around very bright
stars.
