imap_processing.spice.time.sct_to_ttj2000s

imap_processing.spice.time.sct_to_ttj2000s(sclk_ticks: float | Iterable[float]) → float | ndarray

Convert encoded spacecraft clock “ticks” to terrestrial time (TT).

Decorated wrapper for chained spiceypy functions unitim(sct2e(), “ET”, “TT”) that vectorizes the functions in addition to wrapping with the @ensure_spice automatic kernel furnishing functionality. https://naif.jpl.nasa.gov/pub/naif/toolkit_docs/C/cspice/sct2e_c.html https://naif.jpl.nasa.gov/pub/naif/toolkit_docs/C/cspice/unitim_c.html

Parameters:

sclk_ticks (Union[float, Iterable[float]]) – Input sclk ticks value(s) to be converted to ephemeris time.

Returns:

terrestrial_time – Terrestrial time, seconds past J2000.

Return type:

np.ndarray[float]
