What is the connection between the SEN field in the VIDF file and the N_SEN field in the header record?
The SEN field in the VIDF file is defined as the maximum number of sensors which will be defined in the IDFS data set. However, not all of the sensors that are defined may be returned. Perhaps a subset of the sensors is currently being returned, or there is a rotation amongst the sensors that are being returned. To reflect this situation, the N_SEN field in the header record is meant to serve as the indication as to the actual number of sensors being returned and the SENSOR_INDEX field in the header record specifies the sensor numbers for those being returned.
