The observations successfully traced an outburst decay in which the source luminosity decreased almost monotonically from $\\sim 10^{37}$ erg s$^{-1}$ to $\\sim 10^{34}$ erg s$^{-1}$, by $\\sim 3$ orders of magnitude. To investigate luminosity-dependent changes in the accretion geometry, five of the seven data sets with a typical exposure of $\\sim 18$ ks each were analyzed; the other two were utilized in a previous work \\citep{Sakurai2012}.
