Preliminary Chandra spectral observations

These spectra were created just averaging the -1,+1 orders, and leaving out only spectral regions where the S/N was too low.

In some cases, the spectra have been divided into multiple spectral regions. Some smoothing was applied in the images. Data are from the publicly available Chandra database. , except those produced by D. Huenemoerder .

Use the middle-mouse button to change the orientation to Seascape, inside ghostview.

Use shift-left button to download the files.

Enjoy !
