Group: /tofx<br />
This group contains data specific to the each TOF card. Card-specific data types include TOF Status and Oscillator Correction data. There is one<br />
instance of this group for each card used to collect data.<br />
Group: /tofx/osc_corr<br />
This group contains the derived <strong>L1B</strong> oscillator correction data. This correction has been applied to the <strong>L1B</strong> range data within this file. Since the<br />
oscillator correction is TOF hardware-dependent, there is one instance of this group for each TOF card in use.<br />
