IV/29             Identification of Dahlmark variables         (Skiff+, 1997)

Identification of Dahlmark variables. Skiff B.A., Williams G.V. <IAU Inform. Bull. Var. Stars, 4448, 4449, 4450, 4451 (1997)> =1997IBVS.4448....1S +1997IBVS.4449....1W +1997IBVS.4450....1S +1997IBVS.4451....1W
ADC_Keywords: Stars, variable Abstract: The amateur observer Lennart Dahlmark has published a useful series of IBVS notes listing a number of candidate variable stars, most of which were new. Although adequate charts and reliable semi-accurate positions were supplied, no other identifications were usually given. If the stars are to be recovered for further study and linkage within other surveys (IRAS, etc.), then precise positions must be determined to make identification unambiguous within crowded galactic fields.
