Mosflm should read the pixel size from ADSC Q210 images okay (the values
QX and QY above); depending on how old the version of Mosflm is at ID19
(of course, I _should_ know!), it should also work with Q210 images just
by giving the "DETECTOR ADSC" keywords without all the other stuff (e.g.
NX, NY above) in the example mosflm_Q210.inp file on the ID19 web page
(though really old versions won't).
