-Observatories provide observational data as a measured flux or as spectral flux density which needs to be converted to the AB magnitude system in order to be used within NMMA. It is important to distinguish between different spectral filters in order to run a consistent analysis. Current available filters can be checked in [[https://github.com/nuclear-multimessenger-astronomy/nmma/blob/538326458e1e6101389e9861ff6bf19bc93fa070/nmma/em/utils.py#L48|utils.py]].+Observatories provide observational data as a measured flux or as spectral flux density which needs to be converted to the AB magnitude system in order to be used within NMMA.

A specific flux or respective magnitude measurement comes along with a specific time stamp which needs to be in the **ISOT time format**. For further details, see [[https://docs.astropy.org/en/stable/api/astropy.time.TimeISOT.html|here]].
