catchability with power needs correction #260

Closed Rick-Methot-NOAA closed 3 weeks ago

Current text: image

Should be: 3 = Q with power, 2 parameters establish non-linear survey-abundance linkage. y = q * x ^(1 + c). Therefore, c > 0 leads to hyper-stability and c < 0 leads to hyper-depletion.

then If survey units equal 35 or 36 (e.g. index of a deviation), then Q option 5 or 6 will add the value in the 2nd Q parameter to the expected value. If Q option is 6, then the third parameter is used as a power just as in Q option 3.

@Rick-Methot-NOAA We made edits to the catchability section a while back but those won't be shown in the user manual until the next release. Can you review the catchability section in this pdf and let me know if you still want those changes made?

Thank you for remembering. Yes, the edits shown in the pdf correct the issue. No further changes necessary.
