Hi, Rene,
Again about PAW and ROOT compatibility...
Recently I made some projections of 2d-histogramms, and noticed that
in case of 2d-histogram with errors projected histograms in ROOT and PAW
have different errors. I think PAW makes error calculation in this
case more correctly than ROOT: ROOT actually calculates error bars without
any respect to errors in original 2d-histogramm.
Projection in PAW made by:
PAW > prox 8399
PAW > hi/proj 8399
PAW > hi/pl 8399.prox
Projection in ROOT made by:
root [1] h8399->ProjectionX("_px",-1,-1,"e");
root [2] h8399_px->Draw();
May be important: I've used 2d-histograms with errs, produced via HBOOK
package, then convert them into ROOT file by means of h2root utility. But
I've checked the code of H2ROOT and there're lines that convert 2d-errors
from PAW to ROOT...
(ROOT-3.03/08 AFS-version for 7.2 redhat)
Best regards,
Stanislav.
