---|
| 67 | // telescopes (45m or ASTE). |

---|
| 69 | // information from the data. Since header data depends on the telescope and its configuration, |
---|
| 70 | // it is an abstract in this class and is defined in each concrete class. |
---|
| 71 | // On the other hand, the later reads each scan record (set of meta data |
---|
| 72 | // and spectral data). The method uses <linkto class=NRODataRecord>NRODataRecord</linkto> |
---|
| 73 | // to access scan record. It is implemented here since contents of scan record is |
