Operation Date Description

Operations enable reversible modification of data -- they act like filters which process the data. The graph you see above represents the data after these operations have been run. Delete them to undo their effects, or to apply them in a new order.

  • The thumbtack symbol indicates that data has been saved in a snapshot upon running that operation.
  • The symbol indicates that the operation's data snapshot is being referred to by another operation. Click it to learn more.
  • Operations with a #000-style suffix, like subtract:3243#2414 are referring to a specific snapshot (in this example, #2414) of another spectrum. Click to learn more.

Fantastic O2 lines at ~900nm, 760nm and 685nm! 760 especially.

The double line at 717 and 725 that we were wondering about seems to be H20 according to the graph on Wikipedia: https://en.wikipedia.org/wiki/File:Spectrum_of_blue_sky.svg

I think that if it weren't as overexposed in the blue-green region we'd have gotten some of those lines as well.

By the way, the spectrum you took looks really interesting! You cansee the Oxygen absorption aroun 760nm quite well. Although there is a whole world of information in the IR which is not present, where you can see CO2, water vapour and other greenhouse gases: http://www.stellarnet-inc.com/images/solar%20image%20200-2400nm.gif

How was this spectrum taken? How did you get so far into the NIR?
