I thought that after putting together the whole subsector, writing it up, mapping it out, and even putting it on a spreadsheet, that others might be interested in it. So I put cleaned up versions of all my descriptions, and the map into a PDF for you to download. The spreadsheet, which is useful for sorting the planets by any of their coded features is available too!
In putting together my subsector I did use a few resources that didn't come from the starter books. First off, I'm bad at names, and with 49 systems (slightly more than the 50% that I would have rolled statistically) I found a useful name generator - Amaranth Traces and Thraesja SG-1 name generator that helped me fill in my map. I also occasionally used Kinkret Web Dice Roller rather than rolling my own dice.
I also want to thank Alex Schroeder specifically for his subsector mapping program. After I posted my hand drawn map he linked in his comments to it, and I decided to give it a try. It took a few tries to get my data formatted correctly, and Alex had to make a few tweaks to his program to make allowances for some differences between Starter Traveler and Mongoose's edition.
Subsector Map PDF - Check out how much nicer this is than my hand drawn map! There are different trade routes, but I'm totally ok with that, as I was kind of making it up anyway.
I hope that these downloads and links are helpful for anyone interested in Traveller.
