Description: Base class for using jetfit with CMSSW
|
| 9 |
|
|
|
| 10 |
|
|
Implementation:
|
| 11 |
|
|
o Method make_histo is used to prepare a histogram for analysis;
|
| 12 |
|
|
the user can read this from a file or generate from the actual event
|
| 13 |
|
|
o Method make_model_def is used to define a formula and initial
|
| 14 |
|
|
parameters for the model used
|
| 15 |
|
|
o Method analyze_results performs user analysis on results;
|
| 16 |
|
|
the user is given a trouble vector and the original histogram in
|
| 17 |
|
|
addition.
|
| 18 |
|
|
o The function pointer user_minuit defines what to do after each fit
|
| 19 |
|
|
is done. The pointer should be obtained in the subclass constructor.
