// <summary>
// <linkto class=NRODataRecord>NRODataRecord</linkto> is a class 
// that represents a single scan record 
// (scan header + data record) for NRO 45m and ASTE raw data. 
// </summary>

// <use visibility=global>

// <reviewed reviewer="" date="" tests="" demos="">
// </reviewed>

// <etymology>
// NRO and ASTE raw data format consists of two major components; data 
// header and scan record. <linkto class=NRODataRecord>NRODataRecord</linkto> 
// is a representation of the scan record 
// that contains a scan header and a spectral data.
// </etymology>
//
// <synopsis>
// <linkto class=NRODataRecord>NRODataRecord</linkto> is a struct that is an 
// implementation of a single scan record.
// All attributes are public.
// </synopsis>
//
// <motivation>
// <linkto class=NRODataRecord>NRODataRecord</linkto> are defined to import 
// NRO and ASTE raw data effictively. 
// It enable to read scan record all at once instead of to read each 
// attributes individually.
// </motivation>
