The "4-year all-sky X-ray Image" obtained with the Gas Slit Camera (GSC) and Solid-state Slit Camera (SSC) of MAXI in 2009-2013. The colors are soft (0.7-2 keV in red), middle (4-8 keV in green), and hard (8-16 keV in blue) X-rays. More than 500 sources as well as the galactic ridge emission and faint diffuse structures are detected. Red sources are mostly supernova remnants. Orange sources are low-mass X-ray binaries, and bule ones are mostly binary X-ray pulsars. Both 1650V and 1550V data are used. Thanks to the deeper exposure more faint extra-galactic objects have become visible. The image is without correction for exposure.
Notice of erratum:
In the archived MAXI/GSC light-curve data, version 1.4, which had been released since 2012 November to 2013 April 24, the errors on the flux had been incorrectly stored. (They were the halves of those suppoed to be.) The erratum was fixed on 2013 April 26. If you have these light curve data, please download the latest one from our archive page, again.
We apologize for causing the inconvenience.
(2013, April 24)
The same erratum as the above had been revived since 2013 July 22 to 2013 December 20.
We fixed the bug on 2013 December 21. If you have downloaded the light curve data, please update it on our archive site, again.
We apologize for the inconvenience.
