How was the Real-Space map created?

Post by jiggyjiggy » Tue Oct 23, 2018 4:15 pm

I've been looking through the data of the Real-Space map.

I've found that some of the stars' distances are pretty close to their real-life distances, while others are way off.

Why is this so? Was it an attempt to cram more distant stars into the map?

its adapted from a star map from the 8o's. Appreciate how much accuracy in star parallax has improved since then :twisted:

by the way, how were the Cartesian axes aligned with respect to the Milky Way?

hmm, what way would that be?

for example, some charts have the z-axis pointing out of (and perpendicular to) the galactic plane, while the SotS chart's z-axis appears to lie within the galactic plane.

It seems like your original starmap data was using earth-centric equatorial co-ordinates, which is about 60 degrees tilted from earth-galactic co-ordinates
