Abstract:
We present a catalog of near-infrared photometry of young stars
associated with the Ophiuchus molecular cloud based on observations
made with the Hubble Space Telescope NICMOS3 camera at 1.1 and
1.6µm. Our survey covers 0.02deg2 centered on the dense molecular
cores in Lynds 1688. We detect 165 sources at 1.6µm and 65 sources
at 1.1µm within our estimated completeness limits of 21.0 and
21.5mag, respectively.

162634-242330 : S1, a known binary of separation 0.02" (Simon et al.,
1995ApJ...443..625S 1995ApJ...443..625S), was covered by our survey but was unresolved in
our images. It is included in this table for completeness.
162719-244139 : We detect a companion 8.8" from SR 12, itself a binary
of separation 0.28" (162719-244148 and 162727-244048)
