Calceph Earth-Sun distance

This is a small tool to compute earth sun distance based on CALCEPH package.

This project contains two Python scripts:

• solarDistanceComputation.py: A script which uses the CALCEPH library to compute the earth/sun distance. It takes as an input:

  • the ephemeris file(s) to use (examples can be find on https://www.imcce.fr/inpop/)
  • the year of the date for which the solar distance has to be computed
  • the month of the date for which the solar distance has to be computed
  • the day of the date for which the solar distance has to be computed
  • the hour of the date for which the solar distance has to be computed
  • the minute of the date for which the solar distance has to be computed
  • the second of the date for which the solar distance has to be computed

• cmpToDayMonthMethod.py: A script which plots (for a whole year) the solar distance given by the CALCEPH library and a elliptical model method. It also gives some statistics on the difference between those two measures. It takes as an input:

  • the ephemeris file(s) to use (examples can be find on https://www.imcce.fr/inpop/)
  • the year for which the comparison will be done

Requirements

To use these scripts, the calcephpy package must be previously installed.

pip install calcephpy
