The rebin operations performs what can loosely be described as an interpolation from one histogram into another histogram with the same integrated count but with modified X-boundaries. Some numerical precision is lost during a re-binning operation and there is usually a degree of peak broadening so multiple re-binning is to be avoided. The essential element in all the rebin operations is to provide a new set of X-values for the set being re-binned.
All 3 operations create a new set from at least one existing set and have the form:
"new set" = "old set" rebinned
Clicking "Ok" produces the new set and makes it the current set.
This operation ensures the compatibility of two spectra by re-binning one spectrum to the X-values of the other.
Two existing sets must be selected, the first of which is rebinned against the second.
This operation simply acts to trim or expand a set to fit the given range, often useful when a series of sets with different offsets need combining.
An existing set must be selected and the range supplied as two floating point numbers.
This operations allows ranges of linear or logarithmic steps to be specified explicitly.
An existing set must be selecting along with at least one row of floating point bound and step numbers. The first bound of a row must equal the last bound of the previous row. Therefore these values are tied together, i.e. the values are automatically carried forward. The steps can be defined as linear or logarithmetic by selecting the appropriate radio button.
