 Description   

Writing the pfsFiberTrace s fails if the FiberTraces don't all have the same width. Also the datamodel states that the output profiles are of size NROW*WIDTH*NFIBER, so WIDTH must be well-defined.

I assume that this can happen on more or less straight FiberTraces when the FiberTrace center does not cross a full pixel.
the how-to-repeat is
constructFiberTrace.py $PFS_DATA_DIR --rerun XXX/tmp --id visit=1269 -c xOffsetHdrKeyWord=W_FCA_DITHER trace.apertureFWHM=3

My workaround for this problem requires me to reset the trace in a FiberTrace, and that required me to disable a test in setTrace that the width of the trace isn't being changed. This test should be reinstated when this ticket is resolved.

No longer needed (cf. PIPE2D-219)
