histogram <xray-histogram-statement> end
<xray-histogram-statement> :==
slot=<real>
Slot width for the histogram. Default from map: (maximum-minimum)/mbins
rhomin=<real>
Low density limit for the histogram.
Default: the minimum density of the map.
rhomax=<real>
High density limit for the histogram.
Default: the maximum density of the map.
selection=<map selection>
Select subset of map for analysis. Default=(all)
lowfraction=<real>
If non-zero, a density level will be computed such that lowfraction%
of the selected density points are below this level. The level is
stored in the symbol $cutoff.
hresolution=<real>
Predict histogram at this highest resolution.
This should be the high resolution limit used in computing the map.
Default=0
data=<real> <real> ... <real>
Assign histogram data for each bin. If read from a file
the number of data points must be consistent with mbins.
match
Perform histogram matching.
Warning: this will overwrite the original map.
