The flux drop at MJD 56585 might be due to ocultation by the ISS solar paddle.
The data is updated in every 4 hours.
The data was processed with version 6L, where both 1650V and 1550V data
are used. A-system camera 0 (gas leaking camera) and A-system camera 3
and B-system camera 0 (degraded cameras) are also used.
The coverage is increased. However, when A-system camera 0 is used until 57900 MJD,
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 6L,
and the data have smaller error bars, although data gaps appears
for some sources.
