Query: Reanalyses for $^{42-51}$Ca scattering on a $^{12}$C target at $280$
  MeV/nucleon based on chiral $g$ folding mode with Gogny-D1S
  Hartree-Fock-Bogoliubov densities   In the previous paper, we predicted reaction cross sections $\sigma_{\rm R}$
for $^{40-60,62,64}$Ca+$^{12}$C scattering at $280$~MeV/nucleon, since Tanaka
{\it el al.} measured interaction cross sections $\sigma_{\rm I}$ for
$^{42-51}$Ca in RIKEN and determined neutron skin $r_{\rm skin}({\rm RIKEN})$
using the optical limit of the Glauber model with the Woos-Saxon densities. Our
purpose is to reanalyze the $r_{\rm skin}$ from the $\sigma_{\rm I}$. Our
analysis is superior to theirs, since the chiral $g$-matrix folding model (the
GHFB and GHFB+AMP densities) is much better than the optical limit of the
Glauber model (the Woos-Saxon densities). Our model is the chiral $g$-matrix
folding model with the densities scaled from the GHFB and GHFB+AMP densities.
We scale the GHFB and GHFB+AMP densities so that the $\sigma_{\rm R}$ of the
scaled densities can agree with the central values of $\sigma_{\rm I}$ under
the condition that the proton radius of the scaled proton density equals the
data determined from the isotope shift based on the electron scattering. The
$r_{\rm skin}$ thus determined are close to their results $r_{\rm
skin}^{42-51}({\rm RIKEN})$. For $^{48}$Ca, our value $r_{\rm skin}^{48}$ is
0.105 $\pm$ 0.06~fm, while their value is $r_{\rm m}^{48}({\rm RIKEN})=0.146
\pm 0.06$~fm. We take the weighted mean and its error of $r_{\rm
skin}^{48}(\sigma_{\rm I})= 0.105 \pm 0.06$~fm and $r_{\rm skin}^{48}(E1{\rm
pE}) =0.17 \pm 0.03$~fm of the high-resolution $E1$ polarizability experiment
(E1{\rm pE}). Our final result is $r_{\rm skin}^{48}=0.157 \pm 0.027$~fm. Our
conclusion is $r_{\rm skin}^{48}=0.157 \pm 0.027$~fm for $^{48}$Ca. For
$^{42-47,49-51}$Ca, our results on $r_{\rm skin}$ are similar to theirs. Our
result for $^{48}$Ca is related to CREX.
