Hi there!
I want to get double *
pointers to the data stored in some branches in my tree. However, I just discovered that GetV5
is not implemented. I tried making a second call to the Draw
method, but the pointer seems to simply be overridden.
int nevt = tree->Draw("parallax:l:b:pm_l:pm_b","","goff");
double *parallax = tree->GetV1();
double *l = tree->GetV2();
double *b = tree->GetV3();
double *pm_l = tree->GetV4();
double *pm_b = tree->GetV5();
I get
/Users/jgalan/work/ExtraGalactic_day3/DoFit.C:18:23: error: no member named 'GetV5' in 'TTree'
double *pm_b = tree->GetV5();
Any idea how to get the 5th pointer?
Of course I could just copy the contents into another vector then call again to Draw
method with different variables. The questions is if there is a way to avoid the copy.
