Hi Thibaud,
Python is the BEST language for technical programming (especially during the
current home lock-down). I have been doing all my gnomonic work on Python for
some 15 years so I have many gnomonic routines.
I have :
complete Mees routines for solar position, altitude, azimuth, hr angle, etc
all the conversions you might need (date to JD, JD to y/m/d/h/m/s, decimal hrs
to hh:mm, etc),
Solar Az/Alt to x-y position on a planar dial.
Many EoT routines
All are in stand-alone python 2.x routines so may need minor tweaking to
upgrade to python 3 (arguments for print statements need to be enclosed in
brackets). Many of them have graphical output which use a specific python
package - Apple Mac based Nodebox 1.0
If you have an iPhone, I have a neat program that gives all the solar
parameters, EoT, hr angle and count-down to solar noon using the phone’s
location & time. This could easily be converted to Android is you know how ti
access Lat/Long
Are you Windows or Mac based?
By the way, Chris Steyaert (copied above) is converting my Spider Dial code to
work on his python implementation. He knows 100% more about Python than I.....
Best wishes
Kevin
p.s. I also have a vast Excel spreadsheet with all the solar parameters in
6-hourly UTC intervals from year 2000 to 2050, calculated from US Naval
Observatory's MICA program, which I use to check my routines. You might find
this useful
