WFC parallel EPER

For the WFC parallel EPER plot above, the following key shows the actual data points (with amplifier A,B,C,D indicated), power law fits for each epoch, and power law models for future epochs:

This shows how linear the decline is at any particular signal level -- i.e. it is safe to project model into the future.

This shows the fit for the power law multipliers (m) for the parallel tests (add serial?). They are very linear and project reliably into the future.

Temperature test conducted in Dec 2005 to help with the Aft Shroud Cooling System decision.
