Attn LOAF: More possible errors
Well, you can't expect someone to get it perfect the first time.
Anyway, just so you know, I've only got the CIC's scan of the WCP map, so I may be wrong. BTW, the numbers 3 and 9 look alike - but I've managed to discern the difference now, I wouldn't want to force you to redo the whole lot with a different font.
Hawking Sector - Gegarin Quadrant
Gegarin Quadrant vs Gagarin Quadrant? As far as I can see, it's Gegarin, although Gagarin make sense if it's in honour of Yuri Gagarin.
Typo? Cherenokv when should be Cherenkov?
Hawking Sector - Ladyman Quadrant
The Mu Cephei and Sommers systems appear to be switched
Typo? Merell when should be Merrell?
Argent Sector - Shelus Quadrant
Yaeger when it should be Yeager? Probably named after Chuck Yeager, not the callsign.
BTW, what kind of names are Lesnick and Reid for a system?
Argent Sector - Hughes Quadrant
Typo? Schreidt when it should be Schmidt? Never heard of something called Schreidt...
They all look good, at any rate. And now that makes at least 527 systems.
