This plot shows the relation between ABMAGLIM and the total exposure time for the MUSE-DEEP datacube IDPs. The parameter ABMAGLIM is defined by the data products standard as limiting magnitude of the background and is essentially measuring the background noise.
We display values for the DEEP datacubes (combined across OBs), and for comparison also all values from the MUSE OB-based datacubes. In general, the DEEP datacubes have a higher limiting magnitude than the OB-based datacubes (also shown as black dots, and in more detail here).
