MIRIS Pa{\alpha} Galactic Plane Survey. I. Comparison with IPHAS
  H{\alpha} in l = 96{\deg}-116{\deg}
  The Multipurpose InfraRed Imaging System (MIRIS) performed the MIRIS
Pa{\alpha} Galactic Plane Survey (MIPAPS), which covers the entire Galactic
plane within the latitude range of -3{\deg} < b < +3{\deg} at Pa{\alpha} (1.87
um). We present the first result of the MIPAPS data extracted from the
longitude range of l = 96.5{\deg}-116.3{\deg}, and demonstrate the data quality
and scientific potential of the data by comparing them with H{\alpha} maps
obtained from the INT Photometric H{\alpha} Survey (IPHAS) data. We newly
identify 90 H II region candidates in the WISE H II region catalog as definite
H II regions by detecting the Pa{\alpha} and/or H{\alpha} recombination lines,
out of which 53 H II regions are detected at Pa{\alpha}. We also report the
detection of additional 29 extended and 18 point-like sources at Pa{\alpha}. We
estimate the E(B-V) color excesses and the total Lyman continuum luminosities
for H II regions by combining the MIPAPS Pa{\alpha} and IPHAS H{\alpha} fluxes.
The E(B-V) values are found to be systematically lower than those estimated
from point stars associated with H II regions. Utilizing the MIPAPS Pa{\alpha}
and IPHAS H{\alpha} images, we obtain an E(B-V) map for the entire region of
the H II region Sh2-131 with an angular size of ~2.5{\deg}. The E(B-V) map
shows not only numerous high-extinction filamentary features but also negative
E(B-V) regions, indicating H{\alpha} excess. The H{\alpha} excess and the
systematic underestimation of E(B-V) are attributed to light scattered by dust.
