## Multiple spectra Data Section

A multiple spectra data section contains many spectra, obtained in a single observing scan: typically a drift scan across a source, a on-off scan with a multi-beam receiver, or a drift scan with a multi-beam receiver. The data section is considered as a multiple spectra data section is the special section `Data Section Descriptor' is present. It consists of a `R_NDUMP` records (individual spectra); each spectrum has `R_LDATL` line channels, and is followed by a few data associated parameters (`R_LDPAR` words). The length of each record is thus `R_LDUMP=R_LDPAR+R_LDATL`; the total length of the data section should be: `NDATA=R_NDUMP*R_LDUMP`.

The data header presently contains:
