I incorporated a sector called 0-TEST into my program.
If you want to use a sector you generated yourself you have to save it in the following format.
It is important that the values are at exactly the positions you see below, else you will get wrong data.

REM Hex  Name                 UWP       Remarks                                  {Ix}   (Ex)    [Cx]   N     B  Z PBG W  A    Stellar
REM ---- -------------------- --------- ---------------------------------------- ------ ------- ------ ----- -- - --- -- ---- --------------
REM 0101 Zeycude              C430698-9 De Na Ni Po                              { -1 } (C53-1) [6559] -     -  - 613 8  ZhCo K9 V
REM          1         2         3         4         5         6         7         8         9         0         1         2
REM 1827 Terra                A867A69-F Hi Ga [Solomani] Mr                      { 4 }  (H9C+4) [BE6G] BEf   NW - 114 10 ImDs G2 V"

You also have to include the number of systems in Line 1

EXAMPLE

0-TEST.DAT

1
0101 Zeycude              C430698-9 De Na Ni Po                              { -1 } (C53-1) [6559] -     -  - 613 8  ZhCo K9 V


In this case the sector would consist of just one world.
