QUTILITY COTE. See Table 1. The code is based on a first 
subjective estimate of the reliability of the temperatures 
indicated by the BT trace at any particular depth. The 
quality code docs not apply to the charge in temperatyre 
vith depth; all NT's digitized by MODI are presumed to be ac¬ 
curate (mithin the limits of the instrument system) in re- 
soect so the vertical temperature structure. 
MITE: A negative sign preceding the quality code denotes the 
standard precision of read-out of 0.1 degree could not 
be achieved (poor image, blurred trace, etc.)
