Remarks
A spike at 57370 MJD (2015.12.16) is by the leakage of solar X-ray.
Please ignore it.
OAO 1657-41 is contaminated by XTE J1701-407.
Since XTE J1701-407 is normally off, the flux from this region is from OAO 1657-41.
But, XTE J1701-407 made a burst on 55988. The intensity was 0.3 Crab.
The data is updated in every day.
The data was processed with version 7L, where both 1650V and 1550V data
are used.
Evaluation of the shadow of solar paddles are improved. This decreased the
number of dropping data points.
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 normal 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.
