CFHTLS Wide : W1 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 W1: (n,m), (n=-4,+4; m=-4,+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 9 deg. in RA and 8 deg. in DEC
