I dont kwon the diffence between rel-orbit and abs-orbit.Two files may have the same rel-orbit,but abs-orbit is diffent.

Absolute orbits is the number of orbits taken from the beginning of the mission. Relative orbit tells you where you are in the repeating 12-day orbit-cycle.

Thank you！
For the same research point, if the Relative orbit is the same, can it be understood that the incident angle is the same at this point?

If the relative orbits are the same, can I understand that the incident angles of a study are the same? Thank you

Orbit Number: the absolute orbit number considers the orbits elapsed since the first ascending node crossing after launch. The relative orbit number is a count of orbits from 1 to the number of orbits contained in a repeat cycle. The relative orbit number 1 corresponds to the orbit whose ascending node crossing is closest to the Greenwich Meridian (eastwards).
