This page provides access to the x-ray spectral data obtained by Hayabusa XRS. XRS has the 4 main x-ray CCD chips with large effective detection area ( field of view : 3 deg. ), and the 1 sub CCD chip coupled with a standard sample plate due to solar x-ray irradiation monitoring and in-situ calibration.
XRS data are archived in ASCII table format and consist of 4 types of data format as follows;
|Histogram Data ( hst ) :||
x-ray signal stored within one exposure time in each CCD chip
( CCD 0-3: main chips, CCD 4: solar monitor )
In Level-1 data, the channel number and the corresponding CCD count value are available.
|Header Data ( head ) :||supplement information on each observation time|
|HK Packet Data ( hk ) :||instrument status information through one observation date|
|Status Packet Data ( status ) :||instrument status information including temperature through one observation date|
For the content of each data value, please consult the corresponding label file ( lbl ). A detailed description about XRS data set and the calibration information is now in preparation.
