Scientific paper

Extensive survey observations were carried out for H-alpha emission stars in six Kiso Areas in the Orion region. The observations were made using mainly the Kiso Schmidt telescope, and partly using the CTIO Curtis Schmidt telescope. Our surveys extends the limiting magnitude to V=17.5 over an area of 150 square degrees, and the total number of detected H-alpha emission stars were 1157. The celestial coordinates and the V magnitudes were measured along with an eye estimation of the H-alpha intensities. The identification from the previous observations were also made. The brightness distribution, which is peaked around V=15, suggests that they are probable candidates of T Tauri-type stars. (2 data files).
