Below is part of the info from one of my completed tasks. I've read the seti at home science info pages and have a basic understanding of what the apps are looking for and reporting. For example, I know what triplet and gaussian are. Can anyone help define some of the following:

score
unscaled peak power
peak (is this how high the signal spike is?)
period (is this how often a signal repeats?)
+ any other terms you see used below that you'd like to point out what they mean. Thanks!


Here is what part of the task report looked like:
