Since the galactic center region is a crowded region, the light curve of this page
contains many sources.
The flare on 2011 January 21 (MJD 55582) is a flare by SAX J1747.0-2853 (Atel #3123, #3161).
The flare since 2014 January 18 (MJD 56675) is from GRO J1744-28 reported by Atel #5790 and #5963.
The data is updated in every 3 hours.
The data was processed with version 7L, where both 1650V and 1550V data
are used. A-system camera 0 (gas leaking camera) is used until 57900 MJD.
There, the flux has a large uncertainty (a few tens of % in 2-4 keV).
Even in 4-10 keV, the data have larger uncertainty than those in
the other cameras.
After 57900 MJD, A-system Camera 0 is no-longer used in version 7L,
and the data have smaller error bars, although data gaps appears
for some sources.
