__NB: On SA13 there are no bands with multiple observations. We then cannot flag outliers or compared aperture magnitudes to check for difference in aperture coorection between point source et extended objects.

Also, there are no sources, with "weird" magnitude or magnitude error, to flag in this field.__

I. Caveats

 
### I.a. Magnitude errors

I.a. Magnitude errors

xxxxxxxxxx
 
At faint magnitudes (mag > 26), few sources from the __Legacy Survey__ have very large errors on the __aperture and total__ magnitudes. These objects may be unreliable for science puposes.<br>

### I.b. Aperture corrections

I.b. Aperture corrections

xxxxxxxxxx
On SA13 there are no sources with multiple aperture magnitudes. We then cannot look for difference in aperture correction between point-source and extended objects for different surveys.
