Move NSWCalibTools and add NSWCalibData package
Hi,
the NSWCalibTools
package was located in the MuonSpectrometer/MuonCalib
folder in master, but in the MuonSpectrometer/MuonCalib/NSWCalib
folder in 21.3 and 21.9. This MR moves the package into MuonSpectrometer/MuonCalib/NSWCalib
to align master with 21.3 and 21.9. It also adds the NSWCalibData
package which was not yet part of master at all.
Best, Nico
