When we have an observation that consists of data from multiple epochs there is a difference in the polarisation position angle. A consequence is that you cant just stack all the data from different epochs together to make a full sensitivity QU cube.
For the vlow cubes we can make a different QU cube for each epoch and then the cubes can be aligned afterwards. These datasets are not so large so not too much of an issue with archiving.
