# WOW! signal calculation of point source intensity

The WOW! signal's measurement took the average signal strength over 12-second intervals. The average intensity's peak was just over 30-1 signal to noise, meaning that the 12 second interval had an average strength of 30-1. But evidence suggests the signal came from a point source. Has anyone ever done the math to estimate the point source strength? Is this even possible?

• Because the "big ear" was fixed, a point source is pretty straight forward, at least within a range of a certain number of arc minutes. One of the drawbacks to the big ear was that they couldn't point it. It just swept around with the rotation of the Earth. As I recall, scientists awaited eagerly for the next day when it would sweep past that point in the sky again but the next day, and every next day after, there were no more wows. A decade or so later they added the ability to turn the big ear and point it at stuff, in case another wow ever happened, but no such luck. Commented May 9, 2018 at 0:46
• Understood. But the question is whether the actual point source signal-to-noise strength can be estimated from the data, or whether the intensity of the point-source signal can be estimated using the data Commented May 9, 2018 at 0:48

• @CarlWitthoft You're right, someone visiting the astronomy site may not know what the WOW! signal is. Commented May 9, 2018 at 15:49
