 Unit cell parameters were initially obtained from 100 reflections
 (5\% < \q < 20\%) taken from 45 frames collected in three different
 \w regions.
 A full sphere of reciprocal space was scanned by 0.3\% \w steps,
 collecting 1800 frames each at 40 s exposure.
 The detector was kept at 3.88(2) cm from the sample.
 Intensity decay was monitored by recollecting the initial 100 frames
 at the end of data collection and analyzing the duplicate reflections.
