Abstract (from CDS):

We report on a program to obtain Hubble Space Telescope (HST) observations of galaxy-mass gravitational lens systems at optical and infrared wavelengths. Here we discuss the properties of 10 two-image gravitational lens systems (Q0142-100=UM 673, B0218+357, SBS 0909+532, BRI 0952-0115, LBQS 1009-0252, Q1017-207=J03.13, B1030+074, HE 1104-1805, Q1208+1011, and PKS 1830-211). We grouped these 10 systems because they have limited lens model constraints and often show poor contrast between the images and the lens galaxy. Of the 10 lens galaxies, seven are probably early-type galaxies, two are probably late-type galaxies (B0218+357 and PKS 1830-211), and one was not detected (Q1208+1011). We detect the host galaxies of the zs=4.50 lensed quasar in BRI 0952-0115, the zs=2.32 lensed quasar in HE 1104-1805, and the unlensed z=1.63 quasar near LBQS 1009-0252. We fit a set of four standard lens models to each lens that had sufficient constraints to compare isothermal dark matter and constant mass-to-light lens models, and to explore the effects of local tidal shears.
