<<MACHO FFF.NNNNN.NNNN>> Object:*  (SIMBAD class: Star) Note:Microlensing candidates from the MACHO collaboration. The authors first used a format 'LMC NNa' for possible events in the LMC and 'N' in the galactic bulge, 'BLG N' in SIMBAD, but then, since 1995, they used in the MACHO database a format including the year of the event. year 1995, format '95-NN' for events in the galactic bulge (Nos 95-1 to 95-41)
year 1996, formats '96-LMC-NN' and '96-BLG-NN' N=2 in the LMC, N=31 in BLG
year 1997, formats '97-LMC-NN', '97-SMC-NN', '97-BLG-NN' N=1 in the SMC, N=5 in the LMC, N=69 in BLG
Same formats is used in next years. The authors use also an internal numbering format 'FFFNNNN' or 'FFF-A', the complete format been 'FFF.NNNNN.NNNN'. Events detected by DIA (see DIA) but not in the alerts have a 'd' before the event number: ex 95-BLG-d5. Events detected in subsequent analysis of SoDoPhot photometry, but not in the alerts havea 's' before the event number: ex 96-BLG-s16.
