In addition, and to fulfill the requirements from the helioseismology experiments on-board, full time resolution attitude are availble. These files contain pitch and yaw offset from Sun-center with a resolution of 10 times per second, and roll angle offsets from the projection of the Sun's North Pole one time per second. The units are degrees. This is the full time resolution of the attitude parameters as downlinked from the spacecraft. The orbit files provide information about the position and velocity of the spacecraft relative to Earth and Sun.
Predictive orbit is received at the Experimenters' Operations Facility five weeks in advance.
Definitive orbit is available only after one week has elapsed, approximately. As with the attitude CDF files, all the required information to interpret the contents is included within the CDF format. There is a row for each 10-minute entry. Each entry has two lines. It includes the status of the command link, the commands sent to the spacecraft and either the verification of the reception or the reason for they failure.
