$H_0$ from ten well-measured time delay lenses
  In this work, we present a homogeneous curve-shifting analysis using the
difference-smoothing technique of the publicly available light curves of 24
gravitationally lensed quasars, for which time delays have been reported in the
literature. The uncertainty of each measured time delay was estimated using
realistic simulated light curves. The recipe for generating such simulated
light curves with known time delays in a plausible range around the measured
time delay is introduced here. We identified 14 gravitationally lensed quasars
that have light curves of sufficiently good quality to enable the measurement
of at least one time delay between the images, adjacent to each other in terms
of arrival-time order, to a precision of better than 20% (including systematic
errors). We modeled the mass distribution of ten of those systems that have
known lens redshifts, accurate astrometric data, and sufficiently simple mass
distribution, using the publicly available PixeLens code to infer a value of
$H_0$ of 68.1 $\pm$ 5.9 km s$^{-1}$ Mpc$^{-1}$ (1$\sigma$ uncertainty, 8.7%
precision) for a spatially flat universe having $\Omega_m$ = 0.3 and
$\Omega_\Lambda$ = 0.7. We note here that the lens modeling approach followed
in this work is a relatively simple one and does not account for subtle
systematics such as those resulting from line-of-sight effects and hence our
$H_0$ estimate should be considered as indicative.
