X-ray delivery
1 to ~332 pulses at 6 keV, 4.5 mJ
Stable delivery
Number of pulses limited by the Photon Beam Power local limit
that is set to 16 W. Is this intentional? All other limits are set to 40 W

Beam conditions:
Used photon energies between 6 and 7 keV, including short undulator scans
Continuously got 1 mJ despite the short pulse mode
that's running
Bandwidth was found to be 18 eV FWHM at 6.07 keV (0.3%) by monochromator scan against fixed undulator setpoint
