I am using the TNG50 simulation and I wanted to know if there is a way I can read all three subboxes at once when I load the halos and subhalos instead of using TNG50-1, TNG50-2 and TNG50-3 separately. Could I just write TNG50 in the path I have already defined? Or is there another way of doing it more quickly?
Many thanks in advance.
TNG50-1, TNG50-2, and TNG50-3 are three separate simulations: their snapshots and catalogs are entirely separate, and there isn't any way to load data from all at once.
If you want to compare them (e.g. for a resolution convergence study), you should do the analysis on each separately, and then combine the results in a plot.
Note: these aren't "subboxes". We use the word "subbox" to refer to our "subbox snapshots", which are high time-resolution sub-regions.
Thank you, Dylan! And thanks for the explanation regarding the subboxes.
Hi Dylan, I do not understand the difference between these simulations. To extract data from TNG50, do I need to combine the data from all the three or choose just one based on the necessity?
One would typically only use TNG50-1 (the highest resolution version available).
If you want to understand the resolution convergence of your results, it would be typical to then compare to TNG50-2 and TNG50-3.
