## I. Caveats

I. Caveats

 
### I.a. Magnitude errors

I.a. Magnitude errors

xxxxxxxxxx
At faint magnitudes (mag > 24), some surveys have very large errors on the magnitude. These objects may be unreliable for science puposes.<br>
This includes __DES aperture and total__ (at mag > 24) and, for very few sources __VISTA aperture and total__ magnitudes (at mag > 23) and __IRAC1, IRAC2 aperture and total__ magnitudes (at mag > 28). <br>

### II.c IRAC aperture magnitude
​
IRAC1 and IRAC2 bands are available in this field, but there are __no__ sources with exactly the same magnitude (as it is the case in other fields with IRAC observations).

II.c IRAC aperture magnitude

IRAC1 and IRAC2 bands are available in this field, but there are no sources with exactly the same magnitude (as it is the case in other fields with IRAC observations).

### II.b. Outliers
​
There are no bands with multiple observations, so we then cannot flag outliers.

II.b. Outliers

There are no bands with multiple observations, so we then cannot flag outliers.
