The table was created using the observation quaternions expressing the attitude of the instrument, a list of possible targets including both intra- and extra-solar targets, and knowledge about the Field(s) Of View (FOV) of the instrument as expressed in the NAIF/SPICE kernels. The algorithm used to select targets for this table checks if the position of the center of the target body is calculated to be in or near the instrument FOV; near means within about half of the FOV. Note that this simple algorithm may exclude targets when the size of the target is much larger than the FOV. The PRODUCT_ID for any single observation will be listed once for each potential target. All data PRODUCT_IDs will be listed at least once; if no targets are in or near the FOV, then there will be one row with that product ID, and the last four entries will be empty.
