Update solar spectrum?

[dkirkby]

Carlos Allende Prieto has suggested that we adopt the HST CalSpec solar spectrum:

to replace the current data/sky/solarspec.txt. This came up in the context of the specsim scattered moon and twilight sky emission models. Quoting from Carlos:

The solar spectrum looks good, but I have compared it to the one adopted for reference in the
HST calspec collection and the latter shows less wiggles in the near infrared side (at ~ 700 nm).

I have not had a chance to look into this yet (and it does not seem urgent) but chime in if you have opinions or are interested in following up on this.

We could compare to the Kitt Peak FTS solar spectrum as well.

I don't think the FTS has much flux/SED information. The 1994 Kurucz et al. version was calibrated using the low-res. Neckel & Labs data.

Right.
