Re: [IRCA] DKAZ and Flag data

Bill -


I'll try to get around to it shortly, even if I am sick of running the simulations.

Thanks for running this Chuck and to Nick for making the results readable.

I’ll repeat a request I made a few days ago - any chance of adding a column for 1MHz?

My impression is that there is not a linear degradation in gain on the DKAZ but that it falls off more rapidly below 700 or 800 kHz.  Therefore I’m betting a run at 1MHz would have similar values to that at 1.5MHz.
