Interactive tools can be found on next to the plots and were created using
Bokeh. These tools include: scroll zoom, pan, box zoom, save, undo, redo, reset, lasso select and box select.
The plotted period is computed as 2 * orbital period of the source (From
If no data exists, a default period of 200 days is taken instead (see table).
The Fermi undetected data points indicate upper limits.
The light-curve is plotted in an interval indicated in the source title. However, the historical light-curve can be seen as well using following procedure:
- Scrolling back with the mouse
- Using the pan tool of the plot to move to the left
- Zooming in the desired spot using either the mouse scroll or the box zoom tool
MAXI last burst:
Our algorithm is used to identify the last burst recorded in MAXI data. It has following constraints:
- Only MAXI data is used to recognize a burst
- Bursts identified with less than 3 data points are ignored
- Bursts in which data gaps are found which are bigger than twice the orbital period are ignored
If an orbital period is known for the source, a folded light-curve is plotted,
which takes the most recent measurement of all instruments considered and folds two times
the orbital period backwards from there.
Darker colors are used for more recent periods.
MAXI hardness intensity diagram:
Using the identified burst, a HID is computed using the hard (10-20 keV) and soft (2-4 keV) energy bands of MAXI. All negative fluxes are ignored in the plot.
The hardness ratio is calculated using the definition (hard -soft)/(hard+soft) and corresponding errors are computed using Gaussian error propagation.
