Description:
The catalog of 534 Hα emission lines stars in the region of the
Orion Nebula (5°x5°) is presented, an the basis of 240 "new"
Hα stars found on Tonantzintla spectral plates and previous known
Hα emission stars.

Note (3): Coordinates are mainly from UCAC2 and 2MASS, but a few others appear
for very faint or crowded stars and components of close pairs.
Coordinates given to only 1" precision are the mid-point for double/multiple
stars or for diffuse nebulous objects.
Note (4): Position origin as follows:
M = 2MASS (2006AJ....131.1163S 2006AJ....131.1163S, Cat. II/246)
U = UCAC2 (2000AJ....120.2131Z 2000AJ....120.2131Z, Cat. I/289)
T = Tycho-2 (2000A&A...357..367H 2000A&A...357..367H, Cat. I/259)
C = Carlsberg CMC15 (Cat. I/327)
u = UKIDSS DR8 (2007MNRAS.379.1599L 2007MNRAS.379.1599L, Cat. II/314)
S = Sloan Digital Sky Survey DR9 (2012ApJS..203...21A 2012ApJS..203...21A, Cat. V/139)
