cnv 0.2

Parser for .cnv files, the Sea-Bird CTD data format.

Latest Version: 0.3.3

PyCNV
==========================

This is a parser for Sea Bird CTD output files.

The `Sea Bird CTD`_ post processed data usually uses the .cnv extention. The
purpose of the PyCNV is to parse this type of files, considering the different
versions along the time, as well as different setups.

At this point my goal is to have an object with the attributes parsed from the
header, and the data as Masked Arrays, so that the user don't need to loose
time evaluating the version and details of that cnv, but have it in a
standard pattern, ready to use.

Support and Documentation
-------------------------

See the `PyCNV Wiki`_ to view documentation, report bugs, and obtain support.

The `Seasoft`_ manual might be the best reference for the format used.

The variables names were based on the `pcmdi standard name table`
