Where I can find a description of the ancillary data for Solar Orbiter?

import spiceypy

# Define paths to the MK files
predicated_mk_filepath = "solo_ANC_soc-pred-mk.tm"
asflown_mk_filepath = "solo_ANC_soc-flown-mk.tm"

# Predicated SPICE kernels should be loaded first
spiceypy.furnsh(predicated_mk_filepath)
# Then load as-flown SPICE kernels 
spiceypy.furnsh(asflown_mk_filepath)

# Print out the toolkit version
spicespicepy.tkvrsn("TOOLKIT")

# At this stage Solar Orbiter SPICE kernels have been loaded and are ready to be used (visit spiceypy documentation site in https://spiceypy.readthedocs.io to learn more about module capabilities.)

...

N.B. You need SPICE kernels to perform convertion (see related question here)

How to retrieve Solar Orbiter orbit digest CDF files ?

The SOC provides CDF files that contain Solar Orbiter location and speed in HEE and HCI coordinate systems.

These files are made available in the SOC Public Confluence page (https://issues.cosmos.esa.int/solarorbiterwiki/)

A copy of these files are also saved by the LESIA in https://rpw.lesia.obspm.fr/roc/data/private/solo/soc/spice/cdf/ (restricted access)

Where is Solar Orbiter spacecraft currently?
