CFHTLS Wide : W2 pointing description
- Each image is one CFHTLS-Wide pointing, with 1 deg. x 1 deg.
- Assumed: the camera scientific FOV is 1 deg. x 1 deg., as expected from the
optical+megacam design
- Pointings separated by 57' in RA (3' overlap in RA) and
56' in DEC (4' overlap in : larger than in RA to take into
account the 62" gaps between CCD rows during the shift sequences for
each pointing exposure).
- Areas are referred
as W2: (n,m), (n=-3,+3; m=-3,+3) are the RA and DEC offsets
respectively, with respect to the W center position adopted by the
CFHTLS working group (ie: the (0,0) position in the following table).
The total FOV is 7 deg. in RA and 7 deg. in DEC
