This plot shows the relation between ABMAGLIM and the total exposure time for the MUSE 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. </font><p><font size="2">
The parameter is displayed in plot #1 for the SKY-based datacubes; in plot #2 for the OB-based final datacubes (SINGLE or COMBINED).
The plot #2 has both the SINGLE and COMBINED datasets split into the ones with negative background due to 
crowded-field observations, and the "normal" ones with well-behaved background. The crowded-field observations have an over-subtracted background and 
therefore a negative bias on the ABMAGLIM values which is clearly visible on the plots.</font><p><font size="2">
