Pedestal pressure scaling for ST #1290

Description

Samuli Saalerma (EPED author) proposed a new scaling for STEP to capture the pedestal pressure triangularity dependence. It may be very nice to use it to define the pedestal temperature !

Here are the plots data points he gently provided to me:

triangularity:0.2500 0.3000 0.4000 0.5000 0.6000 0.7000 blue criterion: 22.4678 25.9126 38.4566 54.3749 71.6242 98.6992 red criterion: 25.6060 27.6459 37.8634 53.0704 81.3390 110.8707

His message was that both criterion were equivalent for ST at the moment.

Proposal

Implement this scaling and use it :)

Best regards

Please remember that trying to implement pedestal scalings has proved to be a can of worms.
