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 \arcdeg \lesssim b \lesssim + 3 \arcdeg at Pa \alpha ( 1.87 \mu m ) .
We present the first result of the MIPAPS data extracted from the longitude range of \ell = 96 \arcdeg . 5 – 116 \arcdeg . 3 , 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 ( \bv ) 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 ( \bv ) 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 ( \bv ) map for the entire region of the H ii region Sh2-131 with an angular size of \sim 2°.5 .
The E ( \bv ) map shows not only numerous high-extinction filamentary features but also negative E ( \bv ) regions , indicating H \alpha excess .
The H \alpha excess and the systematic underestimation of E ( \bv ) are attributed to light scattered by dust .
