Hi Elena,
What you do cannot work for TH1D or any TH1.
In your script, replace the lines:
TH2F* h1 = new TH2F();
h1->SetNameTitle("h1","phi vs eta");
dt->Draw("MUO.trk.Phi0*180/pi:MUO.trk.Eta>>h1",cmisl);
by
dt->Draw("MUO.trk.Phi0*180/pi:MUO.trk.Eta>>h1",cmisl);
h1->SetNameTitle("h1","phi vs eta");
