I want to get some information about merger history like merger mass and the snap when merger happened. I have noticed that Stellar Assembly have these information but I don't know how to use it to get what I want.
To use this catalog, you should download it, then load the HDF5 dataset corresponding to the snapshot and field of interest.
Hi Dylan Nelson!
Thank you for your reply and I have used it successfully. I notice that ''stars_bonus2_99.hdf5" has the field: ['SnapNumAtAccretion']. Sometimes it returns -1 and somtimes it returns snaps from 0 to 99. I can't figure out what '-1' stands for since I didn't find any description about this file.
These are not part of the public data release - I assume you are working on ISAAC. Please contact Annalisa Pillepich about using these.
