Description
sex -dp says:
#THRESHOLD Detection threshold above background [count] #MU_THRESHOLD Detection threshold above background [mag * arcsec**(-2)]
although
THRESHOLD applies to the detection threshold whereas MU_THRESHOLD applies to the analysis threshold.

This apparent inconsistency comes from the fact that the analysis threshold also applies to the measurement image, which is the one that sets the astrometric calibration. Hence measurements in mag.arcsec$^{-2}$ can only apply to the measurement image, and therefore only to the analysis threshold here.
Hence it is proposed not to change the code, but to set the definition right:
#MU_THRESHOLD Analysis threshold above background [mag * arcsec**(-2)]
The change has been applied locally and will be committed with the next batch of small fixes.
