Hi

I've just been looking at some CBFs produced by CBFLIB 0.6 and 0.7.4 and
noticed some significant differences (these are using "makecbf" on some Q4
images from detector SN 403 SSRL).

makecbf (cbflib 0.6) writes incorrect values of PHI to the CBF -

.img file:
PHI=89.000000;
OSC_START=89.000000;
OSC_RANGE=1.500000;

.cbf file:
loop_
_diffrn_scan_axis.axis_id
_diffrn_scan_axis.angle_start
_diffrn_scan_axis.angle_range
 phi 0.089 1.500

The more recent version 0.7.4 doesn't write this loop, so oscillation
information is missing from the CBF.

Thoughts, anyone?
