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.

It seems way off. And what's with the big bright ultraviolet band? Is this some sort of way of "cheating" by averaging the 600 nm band with the lower 300nm band to get a "hybrid" 532? Or is my calibration wayyyyy off here?

Hey, orienting the image properly makes a huge difference. But why have all my subsequent photos been backwards from my original calibration image?
