Support Seeking Fleet Boat/GUPPY Refit Sonar Info

Ok, I've been trying to mod in Cold Waters a bit and have got a Guppy IIA mostly done... but am unable to find any specifics on their sonar performance.
Specifically, I was looking for notes on their detection capabilities. I've located vague things like 'a snorkling submarine at 20,000 yards' but have been unable to find more specific things like the actual amount of radiated noise that translated into. Does anyone know sources that wouldn't cost an arm, a leg and a couple of toes from the other foot that might get me on track?

I can't give you the exact 1 and 0s behind it but, by 1968, the remaining GUPPYs had all been fitted with BQR-2 / BQS-4 combination, both of them mounted in the "chin" position down below the torpedo tubes. Earlier they had a few different active sets (BQS-2 to name one), and some retained BQR-3 (which was basically war-time JT hand cranked sonar with a cover to cut-down on flow noise / let it operate at a faster speed) for a while.
