  We present a tabulated version of our slim disk model for fitting tidal
disruption events (TDEs). We create a synthetic X-ray spectral library by
ray-tracing stationary general relativistic slim disks and including
gravitational redshift, Doppler, and lensing effects self-consistently. We
introduce the library to reduce computational expense and increase access for
fitting future events. Fitting requires interpolation between the library
spectra; the interpolation error in the synthetic flux is generally $<10\%$ (it
can rise to $40\%$ when the disk is nearly edge-on). We fit the X-ray spectra
of the TDEs ASASSN-14li and ASASSN-15oi, successfully reproducing our earlier
constraints on black hole mass $M_\bullet$ and spin $a_\bullet$ from full
on-the-fly ray-tracing. We use the library to fit mock observational data to
explore the degeneracies among parameters, finding that 1) hotter thermal disk
and edge-on inclination angle spectra offer tighter constraints on $M_\bullet$
and $a_\bullet$; 2) the constraining power of spectra on $M_\bullet$ and
$a_\bullet$ increases as a power-law with the number of X-ray counts, and the
index of the power law is higher for hotter thermal disk spectra; 3)
multi-epoch X-ray spectra partially break the degeneracy between $M_\bullet$
and $a_\bullet$; 4) the time-dependent level of X-ray absorption can be
constrained from spectral fitting. The tabulated model and slim disk model are
