This database table records for each Suzaku observation the different XIS configurations during an observation for all XIS units. The set of parameters that can be configured are: datamode (see also edit mode), window size, on-board window discriminator, on-board grading and event threshold. Each record lists for a given XIS the values set for these parameters in the time interval where they are valid within the observation. Therefore for a given XIS there will be as many records as many different configurations are present within an observation. This database table is generated at the Suzaku processing site. During operation, it is updated on daily basis.
