Opps, turned into a TV ramble

So, not a bad evening. Kangaroos, incl mother and joey outside office, very nice strong double rainbow on town while waiting for bus (with accompanying heavy rain:) and since the Olympics have finished (yes, I know, heresy), decent TV programs.
( ramblings... )

Right, will be good and not say more until n1978 J is callibrated...

hmmph

Bimodal distribution of stellar mean brightnesses is not what I wanted, especially not for calibration purposes. Daft little stars... You're supposed to be constant dammit... Ok, well certain of them are, others aren't, otherwise I wouldn't be studying 'em ... but its not the right sort of variability and not the right stars.
