Celestial Navigation in SH4

[castorp345]

Here's an update to Michael Jones' brilliant python script to include randomization-based error derived from sea state and own speed, as well as to work with Stellarium 0.11.4.

Please note that the attachment as included here needs to have its .txt extension removed (leaving just the .py of course), and that you need to edit the script to include your own proper directory locations!

Also, be sure to input the correct syntax for the date (yyyy:mm:dd), and UTC time (hh:mm:ss), otherwise the script won't load properly into Stellarium.

Many thanks, Michael, for your original work and for providing such a great & fun way to practice plotting fixes without having to lug my C. Plath around!
cheers,
hc
