I used the package successfully with different gravity and magnetic models. However, when I use a magnetic model with file formation version 2, I get an exception of Unknown Version.

Examples of the version 2 format is emm2015 and emm2017.

This is the emm2017.wmm file

WMMF-2

A World Magnetic Model (Format 2) file. For documentation on the

format of this file see

The coefficients are stored in a file obtained by appending ".cof" to

the name of this file. The coefficients were obtained from

EMM2000.COF thru EMM2017.COF and EMM2017SV.COF in the EMM2017 distribution.

ID EMM2017A

Looks like I forgot to add version 2 into the version check. You should be able to try out in the pre-release build later.
