Quick note

Some x-ray work today, using NIST. The difficulty is establishing exactly what is required. I need to define a wavelength or energy grid that provides a smooth baseline over the solar2000 additional grid, then spot and add on any resonances that prove to be important - lines where solar flux is considerably higher/lower than normal, or a particular species is sensitive too.

As these are x-rays, it may be more appropriate to use an energy grid. But as I have a single model that should deal smoothly with x-rays, EUV, visible etc, once its been extended, I need a standardised grid...

More tomorrow
