Compare a signal before an event to after an event

[Lindsey.Wilcox]

Objective: calculate the difference between the average temperature 10 min before an event and the average temperature 10 min after an event

1. Create a condition for 10 min before an event.  This is done in Formula using the .beforeStart() operator.

2.  Create a condition for 10 min after the event.  This is done in Formula using the .afterEnd() operator.

3. Calculate the average during the capsules in the conditions created in Steps 1 & 2.  This is done in the Signal from Condition tool. 

4. Combine the 2 signals created in Step 3 into a single, combined signal.  This is done in Formula using the .combineWith() operator.

5.  Create a condition that contains a capsule for each event, including the 10 min before and the 10 min after.  This can be done in Formula using the .move() operator

6.  Calculate the range of the combined signal using the Signal from Condition tool.
