    How did you calculate these? And how did you validate the results?
    Off the top of my head, if I’d been asked to answer a question like this, I’d have searched through my stack of old discs and found a copy of Redshift. Then had to find a Windows machine to run it on. Then had to find an OLD windows machine to run it on. And only then, I’d have discovered that that version probably didn’t support Martian latitudes and longitudes.
    These days, I’m not sure how I’d attack the question. There are online NASA spacecraft ephemeris tools, I’ve seen them. But whether they’re the right tool for the job.

      Calculated with the SPICE kernels provided by NASA/JPL on the website http://naif.jpl.nasa.gov/naif/ See the the links for the toolkit (installable on Windows, Mac or Linux) and the data files themselves.

        SPICE ? [Follows links because acronym only means an electronic circuit-emulation something] That looks related to the planetary ephemerides that I glanced at … years ago. I’ve forgotten what the context was now – I think I was trying to work out where one of the Voyagers would do [something interesting].
        Thanks anyway.
