Minor discrepancy in Swarm Product Header

01 August 2014

Please note that the q_STR_VFM values reported in the header files (HDR) of the Swarm magnetometer low rate products recently regenerated with the latest values of the Euler angles (from launch to 4 July 2014 with the schema SW_OPER_MAGx_LR_1B and file counter 0302) are not correct.

The correct q_STR_VFM values to be taken into account, and that were used to process the MAGxLR 0302 data, are reported in the following table:

Satellite A [q_STR_VFM]
    [Q1]-0.013231661342904[/Q1]
    [Q2]0.618887980270184[/Q2]

Satellite B [q_STR_VFM]
    [Q1]0.011665364843673[/Q1]
    [Q2]0.619618032648957[/Q2]

    [Q4]0.784683273741830[/Q4]

Satellite C [q_STR_VFM]
    [Q1]-0.001666461237559[/Q1]
    [Q2]0.621375398504043[/Q2]

    [Q4]0.783502485166580[/Q4]
[/q_STR_VFM]

Please note that starting from the 5 July 2014 the data q_STR_VFM values reported in the header files of the SW_OPER_MAGx_LR_1B and file counter 0301 are correct and aligned with the one provided in the table above.
