J/ApJ/566/993 rho Ophiuchus (Lynds 1688) cluster NICMOS imaging (Allen+, 2002) ================================================================================ Hubble space Telescope/NICMOS imaging survey of the Ophiuchus (Lynds 1688) cluster. Allen L.E., Myers P.C., di Francesco J., Mathieu R., Chen H., Young E. =2002ApJ...566..993A ================================================================================ ADC_Keywords: Stars, pre-main sequence ; Photometry, infrared Mission_Name: HST Keywords: infrared: stars - ISM: individual (rho Ophiuchi) - stars: formation - stars: pre-main-sequence 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 1.6{mu}m. Our survey covers 0.02deg^2^ centered on the dense molecular cores in Lynds 1688. We detect 165 sources at 1.6{mu}m and 65 sources at 1.1{mu}m within our estimated completeness limits of 21.0 and 21.5mag, respectively.
