The one-week-binned light curves in this page were created by rebinning the MAXI public one-day-light curves (available at by using the formula,
which is only appropriate if the following two conditions are fulfilled:
Condition 1. Raw data are background dominant;
Condition 2. Background rates are constant (at least, during the time span of rebinning, that is, one week).
To make one-week-binned light curves for scientific papers without assuming the two conditions, we need to go back to event files with effective exposure information, or light curves with effective exposure information.

1. One bin per week: II Peg (JNAME: J2355+286)

(only with statistically rich bins, each including at least four day-bins.)
