PAUS

PAUcam

PAUCam is an optical imaging camera to be used at the prime focus of the William Herschel Telescope (WHT).

• FOV 1 deg x 1 deg
• Pixel Scale 0.265″
• 18 Hamamatsu Fully-Depleted 4K x 2K CCD detectors

The camera is installed with 6 large ugrizY filters covering each the total focal plane and 5 trays containing 40 narrow band filters (10 nm) covering the range between 450-850 nm on the 8 central CCDs. Additionally, there is the possibility to install two external custom filters.

PAUS

• survey with PAUCam
• a 100 deg2 PAUS will provide 3 million redshifts to iAB>22.5 (30 times more than currently available)
• a 100 deg2 PAUS with 45 color bands is equivalent to 4500 deg2 single band imaging survey
• Observe ∼100 deg2 to iAB ≈ 23-24 to reach a volume of 0.3-0.5 (Gpc/h)3 with a few million redshifts split into 3 to 4 wide fields (of several tens of deg2 each)
• where Broad-Band (BB) photometric measurements have already been obtained by CFHTLenS and KiDS, and in which spectroscopic redshifts for calibration are available from the GAMA, VIPERS, DEEP2 and zCOSMOS redshift surveys.
