-SOAR (and institute mirrors):+Data releases: 
 + 
 +  * All L1+ files with their latest versions (at a given date) are collected in a data release 
 +  * The releases are provided under https://​spice.osups.universite-paris-saclay.fr/​spice-data/​ 
 +  * The latest release is updated with new data as they arrive ​(and after a superficial validation step)
 +  * Each release includes release notes, and a CSV catalog of the files in the release. 
 +  * The SPICE data used in a publication have to be cited properly. How to do this is explained in the release notes. 
 + 
 +SOAR:

 +  * SOAR has a TAP interface that can be used for automated queries
 +  * The ''​sunpy-soar''​ Python module uses this TAP interface for queries through SunPy/Fido

 +===== 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.
