... Abstract Determine the set of osculating conic orbital elements that corresponds to the state (position, velocity) of a body at some epoch. ... In general, the elements found by this routine can have two kinds of problems: - The elements are not accurate but still represent the input state accurately. ... One recommended "sanity check" on the outputs is to supply them to the CSPICE routine conics_c and compare the resulting state vector with the one supplied to this routine. ...

The determination of the detector parameters is based on sets of images of a spatially uniform-illumination scene (flatfield frames) and without any illumination (dark frames), putting a plug in place of the filter, taken at a series of exposure times. ... We interleave before and after each exposure time in the series of flatfield frames a set of reference images at an exposure time of 1 sec to determine the possible temporal variation of the illumination level. ...
