Input Files

1. (Mandatory) A FITS event list which contains at least two columns, one of which is named TIME. Usually this will be expected to contain at least three columns, the TIME column plus two others giving image $x$ and $y$ coordinates.
2. (Optional) A FITS total-flux image made previously from the event list. The data type may be any of those output by evselect, eg int8, int16, int32, real32 or real64. The bounds and size in pixels of this image must be the same as specified for the variability image via the relevant evarimgen parameter settings.
