Description: | Coinciding with a tech visit to the site, the instrument suffered a step function in the
data. After the "step" the relative intensities dropped across all channels, and the
relative position changed for channel 415 as well. Investigation into the cause of the step
has yielded no answers.
In the end this will likely be nothing more than a curiosity as the Langley plots and
calibrations are not dependent on absolute calibration. |
