HALO position and attitude

Data access

Some of the data, like the preliminary data of the HALO-(AC)³ campaign, is stored on the (AC)³ nextcloud server. This requires username and password as credentials (registration) that need to be loaded from environment variables.

import os
ac3cloud_username = os.environ['AC3_USER']
ac3cloud_password = os.environ['AC3_PASSWORD']

import ac3airborne

Get the flight segments. We need to load an older version that includes the HALO-AC3 flights. The version labeled latest only holds flights from campaigns pre HALO-AC3.
