+# The following excel files need to be saved in the folder where the .sqlite file is saved:
 
 event_dict.xlsx:
 - this excel file contains information if multiple events are simulated together
@@ -10,5 +10,23 @@ parameter config.xlsx:
 - to use it directly just fill out columns D, J and K
 - the second sheet "sqlite_table_names" contains all names to look for the the MUID to access the parameters
 
+optim_parts.xlsx:
+- contains information regarding what timeframe of the model and sensor data should be compared. The follwing information has to be inserted:
+- label: name of label in reference.csv data
+- event: event name
+- sensor: sensorname, also in label
+- EventWeight: Can be used to givve events a higher weight than other. Default=1
+- Start: Start time of event or the start time of the part of the event that should be calibrated
+- End: End time of event or the end time of the part of the event that should be calibrated
+- Timestep: Of model and measuring data that should be compared
+- Simulation name: Name of simulation if not event name, defined in event:dict.xlsx
+- ResultFile: Link to model result file, relative to folder where the .sqlite of the model is saved
+- ResultReach / REsultNode: Define where the measurement is compared to the model data
+- Result_Column: Name of the Column in which the necessary data is saved on the res1d files. This needs to be changed if a AD or ST model is used.
+- StartOriginal/EndOriginal: If due to cross-correlation other times were used, the original times can be found here
+
+reference.csv:
+- created by the optimization_prepr.ipnyb to get the sensor data for comparison
