This function writes in parallel mode records of a type 103 segment (Chebyshev polynomials of the position and velocity ) in the time scale TCB to the SPK file associated to the ephemeris descriptor eph.
The reservation parameter must be the reservation id returned by the function writeph_spk3_par_reserve().
The target_index parameter is the index of the target in the targets array that was passed to the function writeph_spk3_par_reserve(), starting from 0.
The record_begin_index parameter is the index of the first record to be written in the target's segment, starting from 0.
The record_count parameter is the number of records to be written starting from the record_begin_index.
The polynomials array must have the following structure :
X's 1st coef 1st record |
... |
X's (deg + 1)th coef 1st record |
Y's 1st coef 1st record |
... |
Y's (deg + 1)th coef 1st record |
Z's 1st coef 1st record |
... |
Z's (deg + 1)th coef 1st record |
dX's 1st coef 1st record |
... |
dX's (deg + 1)th coef 1st record |
dY's 1st coef 1st record |
... |
dY's (deg + 1)th coef 1st record |
dZ's 1st coef 1st record |
... |
dZ's (deg + 1)th coef 1st record |

Y's (deg + 1)th coef (record_count)th record |
Z's 1st coef (record_count)th record |

Z's (deg + 1)th coef (record_count)th record |
dX's 1st coef (record_count)th record |
... |
dX's (deg + 1)th coef (record_count)th record |
dY's 1st coef (record_count)th record |
... |
dY's (deg + 1)th coef (record_count)th record |
dZ's 1st coef (record_count)th record |
... |
dZ's (deg + 1)th coef (record_count)th record |
With the 1st record being the record at index record_begin_index, and the (record_count)th record being the record at index record_begin_index + record_count - 1.
Multiple threads can call this function at the same time, but with different values of target_index and/or record_begin_index. The behavior is undefined if multiple threads overlap the written data : e.g., two threads write to the same target target_index and a common record number.
