The validated and 'cleaned' XBT profiles are in section files,
such as xbt122010.asc,which sequentially list all the profiles
with a header 
 2010 12 24  5  6  59.567 -42.867  487
including date (year, month, day, hour, minute),
position (latitude and longitude) and the number of lines (n)
in the profile.

Until xbt082010.asc (August 2010)
the 'Sippican original' fall rate equation is used (at-bt**2),
with a=6.472, b=0.00216
for T7/Deep Blue, the majority of probes;
the following sections used T4 probes:
xbt042000.asc, xbt112006.asc, xbt091999b.asc

Starting with xbt122010.asc (December 2010), 
the Hanawa et al (1995) fall rate equation is used:
with a=6.691 and b=0.00225 (all probes). 

No bias-corrections have been applied on fall rate or temperature.

Files with names ending as f.asc presented excessive noise
and profiles have been filtered: 
- over 11 successive points, the average of the three closest
values to the median is retained and attributed to the mid-point depth.
- data provided as 
z,t,err
where err is the largest differences between the
three points averaged, thus providing an estimate of residual noise 
in the filtered profile

Files xbt091997.asc, xbt101997.asc and xbt031996b.asc include
data from bathythermographs sent in real time 
(with 'Sippican original' fall rate equation)

Data have been collected using a Seas unit.
