All of the TTrees in this file are already friended to the main TTree, "events". You do not need to add the friend trees yourself.

The `logbook`

tree in the main SLAD file is a special tree for holding metadata information about the run. See DocDB 1404 for more details.

TTree | branch | type | comment |
---|---|---|---|

logbook | run_id | int | |

integrated_lifetime | double | by default, not added as friend tree | |

type | char [100] | ||

Edrift | int | ||

extractionHV | float | ||

driftHV | float | ||

sigma_extractionHV | float | ||

sigma_driftHV | float | ||

start_time | char [30] | ||

stop_time | char [30] | ||

Next we list the variables in the other files produced by SLAD. These TTrees are NOT friended to the main "events" TTree. You need to define them as friend trees explicitly. This is demonstrated in the example macros described in Reading SLAD output. These TTrees are kept in separate files because they are either much larger or require extra processing to produce. This allows you to load less data when you do not need the extra files.

### Channel file (RunXXXXXX_chan.root)¶

This file has several TTrees whose branches are arrays of floats.
