1911 1911 Esta clase permite leer datos de espectros desde archivos procesados (.pdata). La lectura
1912 1912 de los datos siempre se realiza por bloques. Los datos leidos (array de 3 dimensiones)
1913 1913 son almacenados en tres buffer's para el Self Spectra, el Cross Spectra y el DC Channel.
1914 1914
1915 1915 paresCanalesIguales * alturas * perfiles (Self Spectra)
1916 1916 paresCanalesDiferentes * alturas * perfiles (Cross Spectra)
1917 1917 canales * alturas (DC Channels)
1918 1918
1919 1919 Esta clase contiene instancias (objetos) de las clases BasicHeader, SystemHeader,
1920 1920 RadarControllerHeader y Spectra. Los tres primeros se usan para almacenar informacion de la
1921 1921 cabecera de datos (metadata), y el cuarto (Spectra) para obtener y almacenar un bloque de
1922 1922 datos desde el "buffer" cada vez que se ejecute el metodo "getData".
