jf = .true.

(so jf(39)==jf(40)==.true) and

iri2016/src/iri2016/src/irisub.for

Line 264 in 28fde0d

C (39,40) = (t,t) hmF2-old, (f,t) AMTB, (f,f) Shubin, (t,f) not used

, iri2016_driver uses "hmF2-old" (BSE-1979?) instead of "AMTB2013" (IRI2016 website default setting) for the F-peak height model.

Is this intentional, or an oversight?
