rss_ringoccs.tools.spm_to_et module

Purpose:

Calculate ephemeris time given a set of SPM values and appropriate kernels.

Dependencies:

1. numpy
2. spiceypy
3. sys

rss_ringoccs.tools.spm_to_et.spm_to_et(spm, doy, year, kernels=None)

Convert seconds past midnight to ephemeris seconds past J2000.

Arguments

spm (np.ndarray):  SPM values doy (int):Day of year of observation year (int):Year of observation

Keyword Arguments

kernels (str):String specifying the appropriate ephemeris kernel file. If None, sets the kernel file to ../../kernels/naif/CASSINI/kernels/lsk/naif0012.tls Default is None.
