 Amit asked me to write down the basic notes of the tutorial on creating a spectrum which I gave him few days ago. As I thought it might be useful for other people as well, I decided to put it in the trac. 
 However please keep in mind that this is far from being complete, might contain information that is valid only now and that it has not been checked for mistakes.

 = Consistent Processing of MC and data = 
 
-[tbc]
+== same processing == 
+
+MC and data should have been processed in the same way (signal extractor, calibration, image cleaning, ...) 
+
+For ganymed, you need star-files as an input. Make sure to use star files from MC and data that had the same processing. 
+
+Information on the different processings can be found in wiki:Processing
+
+== same ganymed == 
+
+Make sure to use either the same ganymed macro or the same setup in the ganymed macro for data and MC. 
+
+In the ganymed macro there is three things that you should make sure are the same: cuts, disp and energy estimator
+
+== same cuts == 
+
+The quality cuts are defined as 'contq' and the background suppression cuts as 'cont0'. 
+
+e.g. 
+https://trac.fact-project.org/browser/trunk/Mars/fact/analysis/mc/ganymed.C?rev=17733#L65
+https://trac.fact-project.org/browser/trunk/Mars/fact/analysis/mc/ganymed.C?rev=17733#L70
+
+Make also sure that you use cuts that have been optimized for the image cleaning you used. 
+
+e.g. 
+old cleaning: /home/isdc/dorner/Tutorial.April2018/ganymed_LP.C 
+new cleaning: https://trac.fact-project.org/browser/trunk/Mars/fact/analysis/ganymed.C?rev=18753#L61
+
+== same disp == 
+
+Make sure to use the same disp parametrization for data and MC. If you don't optimize a disp parametrization yourself, make sure to use the disp parametrization that has been optimized for the cleaning that you are using. 
+
+see https://trac.fact-project.org/browser/trunk/Mars/fact/analysis/ganymed.C?rev=18753#L82
+
+Both version are available there, you just have to use the correct one. 
+== same energy estimator == 
+
+Use the same energy estimator (same method, same file/formula). 
+
