ADC_Keywords: Stars, variable ; Photometry ; Mass loss ; Effective temperatures ; Photometry, infrared Keywords: astronomical data bases: miscellaneous - Galaxy: bulge - infrared: stars - stars: AGB and post-AGB - stars: fundamental parameters - stars: late-type - stars: variables: other Abstract: By cross-correlating the results of two recent large-scale surveys, the general properties of a well-defined sample of semiregular variable stars have been determined. ISOGAL mid-infrared photometry (7 and 15µm and MACHO V and R light curves are assembled for approximately 300 stars in the Baade's windows of low extinction toward the Galactic bulge. These stars are mainly giants of late M spectral type, evolving along the asymptotic giant branch (AGB). They are found to possess a wide and continuous distribution of pulsation periods and to obey an approximate logP-Mbol relation or set of such relations. File Summary:

Note (1): Designation is of the form: ISOGALP Jhhmmss.s-ddmmss (J2000) where P signifies `provisional'. Note (2): Refers to the field, tile, and the sequence number (see Alcock et al., 1999PASP..111.1539A). Note (3): The MACHO light curves show saturation effects. No estimates for Amp and LogP are given. Note (4): BMB denotes Blanco McCarthy Blanco (1984AJ.....89..636B), B denotes Blanco (1986AJ.....91..290B), and the following number is the M giant spectral sub-type. Those marked with ``Mira'' are also listed in Table 1. In some cases we note a second or ``double'' period using the notation: dp(Amp,LogP).

Note (1): "missing" stars probably appeared constant or nonstellar in the MACHO data as a result of saturation and were rejected before the matching stage. Note (2): Mis-id: An apparent MACHO counterpart was mistakenly found during the cross-identification process; the image of the correct star was probably saturated. d: Fragmentary MACHO light curve
