Data filtering

[LiJiang1228]

We can use code to select swarm data which meets criteria (|Dst|<10nT, Kp<2)
request.set_range_filter("Dst",minimum=-10,maximum=10)
request.set_range_filter("Kp",maximum=2)
But, how we can select swarm data which meets (d|Dst|/dt<3nT/hour, d|Kp|/dt<2/3hour)
And, how to select swarm data which meets the local time between 21:00-3:00.

It is possible to filter by|dDst/dt|(absolute value of the rate of change of the Dst index):

request.set_range_filter("dDst",maximum=3) # nT / hour

Unfortunately, it is currently not possible to filter by the rate of change of the Kp index nor by the local time. If you think this would be useful features we might considered to implement them.

Thanks for your answer!
