Abstract:
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.

Note (2): For A0904 and A0976, at three and two epochs of observations,
respectively. The scale of emission intensity is given by the six
grades of 5 (very strong), 4 (strong), 3 (medium), 2 (weak), 1 (very
weak), 0 (absent or doubtful), and 9 means that it lies out of area
on the CTIO plates.
Note (3): "99.9" indicates unreliable magnitude measurement by several
causes, such as unseparated double star image, saturated bright star
image, contamination by nebulosities.
