193?
« on: February 01, 2012, 12:26:34 am »
Hi all,

I have a question about the AIA channels used in the space telescopes. I've noticed that SOHO and STEREO use 195A but SDO uses 193A. As far as I know this is to do with the wavelength emitted by FE XII but does this occur on both 193A and 195A? Why did they change it?

Cheers
