Query: Methodology and Performance of the Two-Year Galactic Plane Scanning
  Survey of Insight-HXMT   The Galactic plane scanning survey is one of the main scientific objectives
of the Hard X-ray Modulation Telescope (known as Insight-HXMT). During the
two-year operation of Insight-HXMT, more than 1000 scanning observations have
been performed and the whole Galactic plane ($\rm 0^{\circ}<l<360^{\circ}$,
$\rm -10^{\circ}<b<10^{\circ}$) has been covered completely. We summarize the
Galactic plane scanning survey of Insight-HXMT for two years, including the
characteristics of the scanning data, the data analysis process and the
preliminary results of the Low-Energy telescope, the Medium-Energy telescope
and the High-Energy telescope. With the light curve PSF fitting method, the
fluxes of the known sources in the scanned area as well as the flux errors are
obtained for each scanning observation. From the relationships of SNRs and
fluxes, the $5\sigma$ sensitivities of three telescopes of Insight-HXMT are
estimated as $\rm \sim7.6\times10^{-11}~erg cm^{-2}~s^{-1}$ ($\rm 3 mCrab,~1-6
keV$), $\rm \sim4.0\times10^{-10}~erg~cm^{-2}~s^{-1}$ ($\rm 20~mCrab,~7-40
keV$) and $\rm \sim2.6\times10^{-10}~erg cm^{-2}~s^{-1}$ ($\rm 18 mCrab,~25-100
keV$) for an individual scanning observation of $2-3$ hours, respectively. Up
to September 2019, more than 800 X-ray sources with various types are monitored
by the three telescopes and their long-term light curves with three energy
bands are obtained to make further scientific analyses.
