Hi TNG team,
I am doing some analysis using TNG50-1-Dark. I found that particle number loaded by il.snapshot.loadSubhalo and il.groupcat.loadSubhalos are different.
You can see that il.groupcat.loadSubhalos gives the same particle number as the website searching gives. But if I load by il.snapshot.loadSubhalo, there is large difference. While I check that my data is complete and correct (using sha256sum -c checksums.txt ), I am wondering why this happens? The ID of this example is 184685 at redshift 1 (snapshot=50). Not all galaxies have this situation but some of them do show the difference.
I solved the problem. That's because my offsets files have some problem
