LSST and Euclid Survey Depths


	u	g	r	i	z	Note	
LSST	23.7	24.9	24.4	24.0	23.5	Depth reached per single visit	
Euclid	25.4	25.6	25.3	25.3	24.9	Average requirement for ground-based complement	
LSST visits	23	4	5	11	13	Number of visits to reach the Euclid depths	
LSST exp. (mn)	11.5	2	2.5	5.5	6.5	Total integration needed (open shutter time)	
LSST time (mn)	15	2.6	3.3	7.2	8.5	Total budget (integration plus overheads)	
Note. We quote the total magnitude for a point source at 5sigma with a PSF fitting photometry.
