MAXI/GSC X線全天マップ
概要
説明
The All-Sky X-ray maps, created using data from the Gas Slit Camera (GSC) aboard the MAXI mission, span 11 years from 2009 to 2020. These maps provide comprehensive coverage of the X-ray sky.
The pseudo-color all-sky map produced by the GSC visualizes X-ray brightness in different energy bands: blue for 2.0−4.0 keV, green for 4.0−8.0 keV, and red for 8.0−16 keV. The data used for these maps have undergone exposure correction and artificial background subtraction.
| Creation Date | Energy (keV) | PI Channel | Data Files |
|---|---|---|---|
| 20200425 | 2-4 | 40-80 | FITS |
| 20200425 | 4-8 | 80-160 | FITS |
| 20200425 | 8-16 | 160-320 | FITS |
The images look apparently dim/bright in order to adjust the color scale for bright/faint sources.
DATA Formats
Data is provided in FITS format as follows.
-
Primary Header
Binary image in Aitoff-Hammer projection using Galactic coordinates, with units of counts cm-2 sec-1. -
Secondary Header
HEALpix image data array in Equatorial coordinates, using NESTED ordering and an NSIDE of 128. TheCNTS columns indicate the X-ray intensity of emissions, also in counts cm-2 sec-1.
