29 | // Currently:
|

30 | //
|
---|
31 | // * MC files: Copy the simulated telescope position (Telescope Theta,
|
---|
32 | // Telescope Phi in MMcEvt) to MPointingPosition
|
---|
33 | //
|
---|
34 | // * Real Data: Copy the nominal poiting position (Nominal Zd, Nominal Az
|
---|
35 | // in MReportDrive) to MPointingPosition
|
---|
36 | //
|
---|
37 | // Future: Interpolate the pointing position for each event between two
|
---|
38 | // consecutive drive reports.
