Natacha,

I have been having the same problem with my Parrot Sequoi, and always with Green band,

Have used Parrot panel calilbration following Pix4D choose best calibration image ([Parrot Sequoia - Choose best calibration image](https://community.pix4d.com/t/parrot-sequoia-choose-best-calibration-image/3612)) and doing processing .

An interesting case I have here. Same area, same flight, almost same hour (10:30 h Rio de Janeiro - Brazil), and have one good result with consistency indes result and other a complete worng.

I would like to understand what is happening.

Thank´s
