MMAP
But another use is for checking out trial solutions taken from the summary lists generated by other indexing programs
The usual guides to which solutions are the most promising are ones like figures of merit, numbers of lines indexed, etc., but only at the position of the refined cell in the map
That’s like having a list of high points in a landscape, and trying to tell tall buildings from natural features with only their heights to go on
Knowing the surroundings of the high-point tells us which are man-made, and similarly which Mmap peak corresponds to the physical solution
