+ | ===== Ephemeris information ===== | ||
+ | |||
+ | You can access ephemeris information from the SPICE headers. For example, the keywords: | ||
+ | |||
+ | DSUN\_AU - distance of the spacecraft from the Sun in AU\\ | ||
+ | EAR\_TDEL - light travel time from the spacecraft to Earth (seconds) | ||
+ | |||
+ | The full list of keywords is given in the [[https://spice.ias.u-psud.fr/spice-data/documents/SPICE-UIO-DPDD-0002-1.4-Data_Product_Description_Document.pdf|DPDD]] - search for "Solar ephemeris keywords". | ||
+ | |||
+ | Users should make sure to correct the SPICE observing times for EAR\_TDEL in order to compare with observations from Earth-orbiting spacecraft. This is especially important for highly-dynamic structures such as flares or CMEs. | ||
