Peter,
GAIA and Skycat seem to have a 0.5 pixel error in their slice (aka
cut) tool. With the attached file create a slice in RA and move it up
and down. The plot changes at the middle of a pixel which is a bit
counter intuitive. Given that it's seen in skycat I'm guessing it
somebody else's problem but can you point me in the right direction?
