[OpenMadrigal-developers] Re: Adding Tsyganenko model to Madrigal

[John Foster]

Bill,

What you've done sounds very useful. I imagine that the TSYG_EQ_XGSM
TSYG_EQ_YGSM points where the field line crosses the GSM XY plane will 
be the most useful for our immediate needs.

A useful back-conversion wuld be to go from a EQ_XGSM, EQ_YGSM position
(inside the Tsyganenko magnetopause) back to geographic lat and long (at
a specified altitude, e.g. 400 km) for a given point in time. Then, we could
take the IMAGE fetures and project them onto our ionospheric TEC
viewing plane.

The last-mentioned features of the Tsyganenko model, don't sound too
useful for our work.

Keep up the good work!
