They provide an index into a potentially long dimension, from the Nexus docs:
In order to make random access to timestamped data faster there is an optional array pair of cue_timestamp_zero and cue_index. The cue_timestamp_zero will contain coarser timestamps than in the time array, say every five minutes. The cue_index will then contain the index into the time,value pair of arrays for that coarser cue_timestamp_zero.
These fields have a different length than the data, so they prevent loading it as a DataArray
. Since they contain no actual information we skip them.
Similar to the same mechanism we use for detector data.
