  The aim of this paper is to provide geoscientists with the most accurate set
of the Earth's astro-climatic parameters and daily insolation quantities, able
to describe the Short-Term Orbital Forcing (STOF) as represented by the
ever-changing incoming solar radiation. We provide an updated review and a
pragmatic tool/database using the latest astronomical models and orbital
ephemeris, for the entire Holocene and 1 kyr into the future. Our results are
compared with the most important database produced for studying long-term
orbital forcing showing no systematic discrepancies over the full thirteen
thousand years period studied.
  Our detailed analysis of the periods present in STOF, as perturbed by Solar
System bodies, yields a very rich dynamical modulation on annual-to-decadal
timescales when compared to previous results.
  In addition, we addressed, for the first time, the error committed
considering daily insolation as a continuous function of orbital longitudes
with respect to the nominal values, i.e., calculating the corresponding daily
insolation with orbital longitudes tabulated {\it at noon}.
  We found important relative differences up to $\pm$ 5\%, which correspond to
errors of 2.5 W m$^{-2}$ in the daily mean insolation, for exactly the same
calendar day and set of astro-climatic parameters. This previously unrecognized
error could have a significant impact in both the initial and boundary
conditions for any climate modeling experiment.
