Algorithm

In the simplest mode (OPT=1) data are simply accumulated in the ratio specified with the outer bin boundaries of each group retained between input and output. In other modes REBIN assumes that the input data are uniformly distributed in each input bin, and donates an appropriate fraction of it to output bins that overlap. Output bins at the edges which are are not completely overlapped are not filled. The QUALITY of each output bin is the logical OR of each contributing input bin. Any output bin which has received no data has its QUALITY set to 'Missing-data'.

Where data are normalised with respect to a given axis (as indicated by the AXIS(n).NORMALISED flag), they are unnormalised (eg. counts/s becomes counts) before being assigned to an output bin, and that bin then renormalised when filled.
