This is done since the data set could have different TIME_OFF * * values for the sensors within the data set. The euler angle software * * assumes that all sensors from the euler angle data set have the same time * * value for all data values. To accomodate this requirement, the current * * algorithm uses the time from the first sensor processed from the euler * * angle data set to dictate the time values, thereby, ignoring the * * TIME_OFFSET values for all other sensors. * * * * INPUT VARIABLES * * struct euler_info *pmi_ptr a pointer to the structure that holds euler * * angle information * * SDDAS_CHAR set_time flag indicating if the data sample is the one * * that controls the timing for the data set * * SDDAS_SHORT which_angle index specifying which of the defined euler * * angles is being processed * * * * USAGE * * ir_same_euler_time (&pmi_ptr, set_time, which_angle) * * * * NECESSARY SUBPROGRAMS * * None * * * * EXTERNAL VARIABLES * * None * * * * INTERNAL VARIABLES * * struct idf_data *ANC_DATA structure holding the data for the ancillary* * data product being processed * * * * SUBSYSTEM * * Display Level * * * ******************************************************************************/ void ir_same_euler_time (struct euler_info *pmi_ptr, SDDAS_CHAR set_time, SDDAS_SHORT which_angle) { struct idf_data *ANC_DATA; /***************************************************************************/ /* Save the time values returned for this angle and this time will be */ /* used for the other angles from this data set. */ /***************************************************************************/ ANC_DATA = (struct idf_data *) pmi_ptr->idf_data_ptr[which_angle]; if (set_time) { pmi_ptr->cur_time.byear = ANC_DATA->byear; pmi_ptr->cur_time.bday = ANC_DATA->bday; pmi_ptr->cur_time.bmilli = ANC_DATA->bmilli; pmi_ptr->cur_time.bnano = ANC_DATA->bnano; pmi_ptr->cur_time.eyear = ANC_DATA->eyear; pmi_ptr->cur_time.eday = ANC_DATA->eday; pmi_ptr->cur_time.emilli = ANC_DATA->emilli; pmi_ptr->cur_time.enano = ANC_DATA->enano; /************************************************************************/ /* This flag is set for the first of the defined euler angles. */ /************************************************************************/ pmi_ptr->copy_next_data = sFalse; pmi_ptr->copy_all_done = sFalse; pmi_ptr->last_comp_frac = 0.0; } /***************************************************************************/ /* Reset the time values to the time defined by the controlling angle, */ /* which is the first angle processed for the data set. */ /***************************************************************************/ else { ANC_DATA->byear = pmi_ptr->cur_time.byear; ANC_DATA->bday = pmi_ptr->cur_time.bday; ANC_DATA->bmilli = pmi_ptr->cur_time.bmilli; ANC_DATA->bnano = pmi_ptr->cur_time.bnano; ANC_DATA->eyear = pmi_ptr->cur_time.eyear; ANC_DATA->eday = pmi_ptr->cur_time.eday; ANC_DATA->emilli = pmi_ptr->cur_time.emilli; ANC_DATA->enano = pmi_ptr->cur_time.enano; } }
