The difference between July on-orbit MPD calibration and prelaunch calibration is show at the following two plots:


 

 
 

SO, pre-launch MPD coefficients are bigger than the on-orbit ones and now (using pre-launch MPD coefficients) the reconstructed CAL energy is overestimated, especially for small diodes.

The difference between October and July on-orbit calibrations is shown on the two following plots:

The change in MPD calibration over 3 month is not big ~1.5-2.0% and goes in opposite direction - closer to pre-launch calibration.
Anyhow for consistency it is suggested to use the new MPD calibration file.
