I think I get what you're saying.
The first thing - system density - is not there. On page 14 it references the Core book and the Sector Construction Guide for determining system density. (So as it explicitly says, out of scope: dealing with individual hexes in this book , not subsectors or sectors).
So second thing, no difference in probability of a star type occurring based on density. If a system is indicated at whatever density is determined, then use the System Determination table on page 15 and Roll on the 2D on the Type column. If the result is a 2, roll on the Special column, or, optionally choose to roll on the Unusual Column instead. On a roll of 12, roll on the Hot column.
In the Special Circumstance chapter, the empty hex contents are based on the system density determined for the region, but again, the odds of all types of objects are related to the pre-established system density.
There are probably multiple competing factors that could skew the types encountered at various densities, including the special case of a globular cluster where all or most stars have one (or two) set age. Not sure how many scenarios and factors there would be, so it's not worth the extra complexity if the results aren't liable to match 'reality' any more than the location of Deneb does (sorry, non sequitur from an entirely unrelated conversation, but in 'reality' Deneb should be about another 12 sectors to Spinward). If you want to add differences based on density for your system determination, feel free, but I think your example 2D table has too low a probability of standard systems.
Hi Geir,
It's a shame you did not take on density. My example I posted was just something I played with while on lunch and not intended as a final by any means, just a "perhaps".
I have downloaded all objects in the sinbad database, out to a 1000pc radius of earth, mostly to get a representative example of how often items occur within our nearby stellar neighbourhood (plus I am looking at updating my nbos project). The concept being to have a map based upon our cross section of the local arm, in a full Miller projection.
It will require a bit of work on my part, given the number of objects, and will necessitate my changing your "one system per hex" limit, as that does not work even in close proximity (150 ly) of earth.
I hope that Mongoose gets their ORC/OGL/TAS license work complete soon, as I have a number of things I would like to actually share, but, don't want to cause issues due to miscommunication over license terms.
An example, is your "decimal orbits". I would have created a "IISS 3rd Survey 1106" (or something like that) which converted the 42 decimal orbits into integers ie

The decimal orbits come from the Companion and Close orbit random placement rolls, but they could also hold planets.
Gas Giants have been found orbiting within the "Sub 1" orbit ranges, some with temperatures hotter than the surface of SOL.
What was previously conceptualized as the "Trojan zone" where the temperatures are hot enough that anything orbiting would effectively be liquid due to the melting temperature of most materials, has now been found to exist with planet sized objects, not just the small asteroid belt objects as originally conceptualized.
I would also base the distances on "from the surface of the star" vs. "from the centre of the star" as many stars are far larger or smaller than our own system. Some stars would have their surfaces in orbit 8 of the original Traveller system.
The above system would also allow for useful orbits on smaller stars.
