Looking for a couple of expressions

[Stefan Gofferje]

Hi,

I am currently working on expanding saakeskus.fi and I would like to
plot some more chaser-specific charts.

Does anyone have links, other sources or maybe even ready expression for
interesting parameters like shear, SRH, etc...?
I am also planning for an "under the hood" page at saakeskus.fi which
will list the expressions I use and provide links to further information.

Greetings from Finland,
