SURVEY OBSERVATIONS OF EMISSION-LINE STARS IN THE ORION REGION .3. THE KISO AREAS A-0975 AND A-0976

As a succession of our extensive survey for H-alpha emission stars in the Orion region, we present the results for the Kiso sky areas A-0975 (5-degrees x 5-degrees, centered at alpha = 5h20m, delta = -5-degrees) and A-0976 (5-degrees x 5-degrees, centered at alpha = 5h20m, delta = -5-degrees). Observations have been conducted using the Kiso Schmidt telescope and partly the CTIO Curtis Schmidt telescope. The numbers of detected H-alpha emission objects are 191 and 415 for areas A-0975 and A-0976, respectively, among which 154 in A-0975 and 122 (including 4 suspected) in A-0976 are new findings in the present survey. The celestial coordinates and the V magnitudes are measured for the detected objects, along with eye estimation of the H-alpha emission strength. Based on the magnitude distribution around V = 14-16, most of the detected emission-line stars are supposed to be T Tauri-type stars. It is found that the emission-line stars are distributed widely around the Orion A complex and its west side. A rather uniform distribution of emission-line stars in area A-0975 is notable, as seen in its north neighboring area A-0903.
