X-Ray variables OGLE Monitoring (XROM) system is a new OGLE real time data analysis utility designed to provide real time photometry of optical counterparts of X-ray sources located in the fields observed regularly by the OGLE-III Survey (SMC, LMC, Galactic bulge).
The list of monitored objects can be easily extended. Input from the astronomical community is most welcome. The photometry is updated regularly, after every clear night.
The photometric data are taken in the I-band. They come from provisional image reduction obtained in almost real time at the telescope and are only roughly calibrated. For calibrated mean magnitudes of presented objects we refer to the OGLE-III Photometric Maps (e.g. Udalski et al. 2008, Acta Astron., 58, 89). However, please note that the object numbering in the final OGLE-III photometric databases is different than in presented here provisional photometry, so the cross-identification must be done according to RA/DEC coordinates.
Photometric data presented here can also be found on OGLE Data download site or on Anonymous FTP Archive.
If you have any questions or comments, send us a message.
The OGLE XROM photometry is provided here for information purposes only to facilitate the community monitoring the X-ray optical counterparts and follow up observations. Please contact us if you want to use the data for publication. We may require to be co-authors when our photometry is important for analysis.
When referring to the OGLE XROM system, please cite the paper by Udalski, 2008, Acta Astron., 58, 187 and provide the WWW address of the XROM system or the OGLE WWW home page.
The following table contains the current list of monitored objects.
