* McIDAS documentation
* </a> for the <a href="http://www.esa.int/SPECIALS/MSG/">MSG Instrument</a>
* did not reflect that calibration data is now stored by band in the
* calibration block.
* </p>
* <p>
* Current understanding is that an MSG ASCII calibration block should be
* prefixed by the string MSGT followed by the following 6 values for the
* Inverse Planck Funciton corresponding to each band:
* <br/><br/>
* <table border="1" cellpadding="2">
* <tr><th>Name</th><th>Calculation</th><th>Units</th></tr>
* <tr><td><b>C1W3</b></td><td colspan="2">C1 * W^3</td></tr>
* <tr><td></td><td>C1 = 2.0e5 * P * C^2</td><td>radiance/(cm^-1)^3)</td></tr>
* <tr><td></td><td>W = 1.0e2 * (band wave numbers)</td><td>(cm^-1)</td></tr>
* <tr><td><b>C2W</b></td><td colspan="2">C2 * W</td></tr>
* <tr><td></td><td>C2 = P * C / B</td><td>K/(cm^-1)</td></tr>
* <tr><td></td><td>W = 1.0e2 * (band wave numbers)</td><td>(cm^-1)</td></tr>
* <tr><td><b>ALPHA</b></td><td colspan="2">gain adjustment</td></tr>
* <tr><td><b>BETA</b></td><td colspan="2">bias adjustment</td></tr>
* <tr><td><b>GAIN</b></td><td colspan="2">gain</td></tr>
* <tr><td><b>OFFSET</b></td><td colspan="2">offset</td></tr>
* </table>
* <br/>
* Where C = speed of light, P = planck constant, B = Boltzmann constant.
* </p>
* <p>
* Each string value is 17 characters with 10 decimal places (fortran E17.10),
* and should be parseable using <code>Double.parseDouble</code>. After
* converting cal block from ints to a string calibration values for the first
* band, including the header should look like:
