Extend CK theta resolution range for RICH1 calibration

RICH1 resolution in data is a little larger currently than expected, and thus the range of the calibration histogram needs to be extended a little to get a good handle on the background shape.

Should be tested with Moore!2308 (merged) and Rec!3408 (merged) which are also needed to allow the photon probability cuts to be loosened when running the Online photon selection cut set.
