The transient 4U 1630-472 is in the same region as MAXI J1631-479.
The 0.6 Crab flares every 600-1000 days are from 4U 1630-472.
MAXI J1631-479 appeared on 2019 January 23 (= 58506 MJD) (ATel #12421).
The data is updated in every 4 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.
