The scale factor is printed, in INTEGRATE.LP, for every frame (column 3). This plot shows spikes indicating that the spindle went too fast every 13 frames or so (but the spindle went a bit slower in the adjacent frames). Needless to say, this problem is quite detrimental to data quality - the reflections which contribute to those frames that went too fast are underexposed.
