IPs Sorted by Gaia EDR3 Distances

The table below lists 67 of the 71 confirmed/ironclad IPs from the 2021 version of the IP catalog in the order of Gaia EDR3 distances. The distances towards the bottom of this table should be taken with caution.

There are four objects for which no Gaia distances are not available: XY Ari, V1674 Her, CXOGBS J174954.5-294335, and IGR J18151-1052, Of these, XY Ari is likely to be nearby: Littlefair, Dhillon & Marsh 2001 estimated it to be at 270+/-100 pc, putting it around 10th on this list (but possibly as high up as fourth).
