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.

I'm still not sure how to calibrate this with Warren's spectra from NIST. I don't seem to be able to use that Lead spectra, because it is not one that i generated myself

Oh, sorry i had missed these comments! lets talk tomorrow night. you should be able to clone calibration from any other NIST spectrum:

OK rad, i fixed the calibration search function and calibrated this one (i'm an admin) -- we should talk to Andy Z from the Bucket Brigade about what elements to look for - he wanted to help compile a list.
