Remarks
There are periodic increases in 2-4 keV flux after 56050 MJD. It is systematic
due to insuficcient calibration of A-camera No.2. Its 4-10 and 10-20 keV bands are correct.
This camera observes Sco X-1 in 7 days out of 70days (ISS orbital precession cycle).

There is a flux drop in 2-4 keV and an increase in 10-20 keV in 56470-56500 MJD.
It is systematic due to gas leakage (gas-gain rise) of A-camera No.0.

There is a flux drop in 2-4, 4-10, and 10-20 keV around 57010 MJD (2014.12.19).
It is due to a series of bad scans due to a bad combination of scan direction and sun avoidance.

The daily, weekly and monthly images are created for every day.
The data was processed with version 5L, where both 1650V and 1550V data
are used. A-system camera 0 (gas leaking camera) is also used.
The coverage is increased. However, when A-system camera 0 is used,
the flux in 2-4 keV has a large uncertainty (a few tens of %).
Even in 4-10 keV there is larger uncertainty than those in the other cameras.
The data is updated in every day.
