FREQUENCY_ID TpInt Data description

NUM_CHAN TpInt # channels Data

CENTER TpDouble (NUM_CHAN) Hz FREQUENCY Center frequencies for each channel in the data matrix.

RESOLUTION TpDouble (NUM_CHAN) Hz FREQUENCY The effective noise bandwidth of spectral channels

REFERENCE TpDouble Hz FREQUENCY The reference frequency. Flags

REST_FREQUENCY TpDouble Hz FREQUENCY The rest frequency (spectral line)

CENTER

Can be non-linear to allow for e.g. AOS

RESOLUTION

The effective noise bandwidth of spectral channels (the frequency resolution of each channel), this may differ from the channel spacing (difference in frequency between the centers of adjacent channels). The Vector nature allows for variable-width channels.
