IR surveys complete to K_s 16

Hello,

I need to find a list of IR sources from images complete to at least
the 16 th magnitude in the K_s (2.15 micrometer) passband. I also need
their J (1.25 micrometer) magnitudes. The list has to come from as
wide an area of the sky as possible. Does anyone know of a survey
which fulfils these requirements?

2MASS only seems to be complete to only about the 14th magnitude.

Thanks

UKIDSS has JHK with K to 18.3.

Thanks.

But UKIDSS doesn't have K_s.

I'm trying to compare images from a suspected star forming region to
other regions. I'm trying to see if the number of objects within a
certain J-K_s color range in these images have more objects than other
areas.

But I also have H magnitudes, and since UKIDSS has H also, maybe I can
compare J-H colors. I'll have to ask my advisor.

Thanks again for your help.
