J/A+A/406/51        ISO long period variables in SMC         (Cioni+, 2003)

Long period variables detected by ISO in the Small Magellanic Cloud. Cioni M.-R.L., Blommaert J.A.D.L., Groenewegen M.A.T., Habing H.J., Hron J., Kerschbaum F., Loup C., Omont A., van Loon J.T., Whitelock P.A., Zijlstra A.A. <Astron. Astrophys. 406, 51 (2003)> =2003A&A...406...51C

These stars belong to the ISO Mini-Survey catalogue of the Magellanic Clouds (ISO MCMS, Loup et al., in preparation). Most of them are in the asymptotic giant branch (AGB) and supergiant phases. The dominant period and amplitude of pulsation have been derived and the stars have been classified as Mira or Semi Regular pulsators. Description: Table1.dat lists the MACHO counterparts of the ISO-MCMS sources. Table4.dat provides the DENIS, 2MASS and ISO magnitudes of the LPVs with an ISO counterpart in the SMC. It also indicates the absolute bolometric magnitude and the parameters that characterize the periodic variation such as: period and amplitude. There is a flag that indicates the type of light-curve and a factor that indicates the quality of the period determination. File Summary:
