Specify each input dataset in response to the prompt INP= finishing with a NULL (!).
Data arrays may be n-dimensional, and are merged along their axes. The arrays must be of the same dimensionality, but the length of each dimension may vary. For the results to be meaningful all datasets must have their axes in the same order.
At present the program looks for BASE_TAI to determine time offsets between the datasets and checks that axes have the same units in all datasets.
The merged dataset should be immediately REBINed to to combine overlapping regions, and sort out the axis values.
This routine should be run only on corrected datasets as it does not modify LIVE_TIME components.
Header data is carried over from the first dataset only.
