56// <etymology>
57// This class actually accesses data from NRO telescopes. This is specialized class
58// for NRO 45m telescope with non-OTF observing mode. In contrast to other concrete classes,
59// both fillHeader and fillRecord methods are implemented here.
60// This is because that the output of non-OTF observing mode is in FITS format and is
61// quite different format from that of OTF observing mode.
62// </etymology>
63//
64// <note>
65// Although the input data is FITS format, the class does not depend on cfitsio library.
