The Wide Field Camera 3 (WFC3) is a fourth-generation UVIS/IR imager aboard the Hubble Space Telescope (HST). WFC3 was installed in May 2009 during HST servicing mission 4, and replaces the Wide Field Planetary Camera 2 (WFPC2).

WFC3 Status

The UVIS and IR Channels are operating nominally.

Please note that the default aperture radius for WFC3/UVIS is 0.4 arcsec (90% of encircled energy). For 80% of encircled energy, use an aperture with radius 0.2 arcsec, comparable to the ACS default.
