I've now replaced the New Reduction Hipparcos data with the brand new Extended Hipparcos dataset, so if you downloaded that previously then please head back and download the new data! Also, my stellar mapping site now proudly bears the Atomic Rockets Seal of Approval!
Iâ€™ve added a new Brown Dwarf dataset to the Stellar Mapping page! This should hopefully be the last major update to the stellar datasets for a while â€“ the next project on the list is to figure out what the reworked Arms for 2300AD might look like based on the realistic data.
I've also made some major updates to the other datasets on the Stellar Mapping page, so if you're using them then you'll want to download the new versions!
