Deep optical imaging of the field of PC1643+4631AandB, I: Spatial distributions and the counts of faint galaxies
We present deep optical images of the PC1643+4631 field obtained at the WHT. This field contains two quasars at redshifts z=3.79 and 3.83 and a cosmic microwave background (CMB) decrement detected with the Ryle Telescope. The images are in U,G,V,R and I filters, and are complete to 25th magnitude in...
