The stacked_seds array

Once the stacking has been performed, the stacked SEDs are saved in an Xarray object, together with all the metadata regarding binning and units. You can check the Getting started for a guide on how to compute stacked SEDs from a galaxy catalog, but you can also just load and return an already existing stack using an Stacker instance:

st.load_stack('path/to/stack_folder')
stacked_seds = st.return_stack()

Of course, you can also load an already existing stacked_seds array directly with Xarray:

import xarray as xr
stacked_seds = xr.open_datarray('path/to/stack_folder/stacked_seds.nc')

Here, we will just show how to access all the relevant information of a stacked_seds array, as generated by stonp. For an in-depth description of the xarray API, please refer to the Xarray documentation.
