Please enter the number of orbits (integer) based on the raan distribution result of the line chart.How use the picture(ranns) to conculate the number of orbits.

Hello! Estimate the number of tracks based on the vertical raan axis of the picture, which requires you to look at the vertical axis of the picture to estimate the number of tracks. In general, the number of "stairs" of a curve is the number of tracks.

For example, in the figure below, the vertical axis ranges from 98.275 to 98.475, so there is 1 orbit:

For example, in the diagram below, the raan on the vertical axis is distributed over 8 "stairs", so the number of tracks is 8:

For example, in the following diagram, raan is distributed on 5 stairs, so the number of tracks is 5:

According to the above method, the raan of all the pictures in the program can be entered into the terminal, as shown in the following figure:

But if there are many tracks, I can't tell the number of steps from the picture, just like the one with 72. Is there any good way to judge?

Sorry, we don't have a better solution to this problem at the moment. Since the satellite trajectory in the real world is not in a strict m x n form, we can only observe it with the naked eye based on the raan information in the TLE data.
