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.

Hey Josh - be aware that only the top edge is being sampled -- so in this example, the moment you took the sample you were getting only a fraction of the light you were getting a few seconds earlier -- it's like a waterfall. Nice data though and plenty to calibrate on.

Thanks for that note! I was wondering if it sampled just a certain time or averaged all that was shown. Is there a way to delete spectra that are loaded on here when I save them, or save them on my computer without uploading them? I don't want to clutter this place with a bunch of junk ones as I figure this thing out.
