Simulation duration: 3110460 s (36 days + 60 s)
Printing time interval: 3024060 s (35 days + 60 s)
Final printing time interval (after "post-facto"): 3024000 s (35 days)
Static gravity field degree: 50

The simulation starts with the date specified above, but the printing starts 1 day later (86400 s later) to exclude the transient effects of the drag free, formation, attitude and pointing control.

Attitude control, formation control, drag free control and pointing control were active.

The accelerometer noises were active. The effects of misalignment, coupling and scale factors were disabled.

The variables of some files have been filtered to remove the aliasing introduced by the undersampling when printing at 1 Hz.
The filter used is a 7th-order Butterworth filter working at 10 Hz with a cutoff frequency of 0.2 Hz.

Files starting with "pendulum_polar_35days_file3..." contain the true quaternion values, the reconstituted attitude measurements, the reconstituted angular velocities and the reconstituted angular accelerations obtained with the "post-facto" module, which performs a "data fusion" between star tracker measurements and accelerometer measurements. The first and the last 30 points have been removed to exclude border effects caused by the inverse filter used for the rephasing of the signal. The other files have been trimmed accordingly.

The output files (ASCII format) are:
- pendulum_polar_35days_file1.dat (filtered variables)
- pendulum_polar_35days_file2a_1.dat (filtered variables)
- pendulum_polar_35days_file2a_2.dat (filtered variables)
- pendulum_polar_35days_file2b_1.dat (filtered variables)
- pendulum_polar_35days_file2b_2.dat (filtered variables)
- pendulum_polar_35days_file3_1_ECF.dat
- pendulum_polar_35days_file3_1_ECI.dat
- pendulum_polar_35days_file3_2_ECF.dat
- pendulum_polar_35days_file3_2_ECI.dat

- pendulum_polar_35days_file4_2.dat
- pendulum_polar_35days_core_omega_1.dat
- pendulum_polar_35days_core_omega_2.dat

The name of the variables are specified in the files:
- Hpendulum_polar_35days_file1.dat
- Hpendulum_polar_35days_file2a_1.dat
- Hpendulum_polar_35days_file2a_2.dat

- Hpendulum_polar_35days_file4_2.dat
- Hpendulum_polar_35days_core_omega_1.dat
- Hpendulum_polar_35days_core_omega_2.dat

Compared with the previous scenarios' data sets, this data set has two new files ("pendulum_polar_35days_core_omega_1/2.dat") containing the true angular velocities of the satellites.

The files are inside the compressed archive "pendulum_polar_35days_29092010.tgz". To extract the files use the following command:
	$ tar -xzf pendulum_polar_35days_29092010.tgz
