/** This class implements the mathematical representation of the 2001
* Naval Research Laboratory Mass Spectrometer and Incoherent Scatter
* Radar Exosphere (NRLMSISE-00) of the MSIS® class model.
* <p>
* NRLMSISE-00 calculates the neutral atmosphere empirical model from the surface
* to lower exosphere (0 to 1000 km) and provides:
* <ul>
* <li>Exospheric Temperature above Input Position (K)</li>
* <li>Local Temperature at Input Position (K)</li>
* <li>Total Mass-Density at Input Position (kg/m³)</li>
* <li>Partial Densities at Input Position (1/m³) for:
* <ul>
* <li>He,</li>
* <li>H,</li>
* <li>N,</li>
* <li>O,</li>
* <li>Ar,</li>
* <li>N2,</li>
* <li>O2,</li>
* <li>anomalous oxygen.</li>
* </ul>
* </li>
* </ul>
* <p>
* The model needs geographical and time information to compute general values,
* but also needs space weather data:
* <ul>
* <li>mean and daily solar flux,</li>
* <li>geomagnetic indices.</li>
* </ul>
* <p>
* Switches can be used to turn on and off particular variations:<br>
* 0 is off, 1 is on, and 2 is main effects off but cross terms on.<br>
* The standard value is 1 for all the 23 available switches.<br>
* Function of each switch according to its number:
* <ul>
* <li>#1 - F10.7 effect on mean</li>
* <li>#2 - Independent of time</li>
* <li>#3 - Symmetrical annual</li>
* <li>#4 - Symmetrical semiannual</li>
* <li>#5 - Asymmetrical annual</li>
* <li>#6 - Asymmetrical semiannual</li>
* <li>#7 - Diurnal</li>
* <li>#8 - Semidiurnal</li>
* <li>#9 - Daily Ap [**]</li>
* <li>#10 - All UT, longitudinal effects</li>
* <li>#11 - Longitudinal</li>
* <li>#12 - UT and mixed UT, longitudinal</li>
* <li>#13 - Mixed AP, UT, longitudinal</li>
* <li>#14 - Terdiurnal</li>
* <li>#15 - Departures from diffusive equilibrium</li>
* <li>#16 - All exospheric temperature variations</li>
* <li>#17 - All variations from 120 km temperature (TLB)</li>
* <li>#18 - All lower thermosphere (TN1) temperature variations</li>
* <li>#19 - All 120 km gradient (S) variations</li>
* <li>#20 - All upper stratosphere (TN2) temperature variations</li>
* <li>#21 - All variations from 120 km values (ZLB)</li>
* <li>#22 - All lower mesosphere temperature (TN3) variations</li>
* <li>#23 - Turbopause scale height variations</li>
* </ul>
* [**] Switch #9 is a bit specific:
* <ul>
* <li>set to 1, the daily Ap only is used (first element of ap array),</li>
* <li>set to -1, the entire array of ap is used, including 3 hr ap indices.</li>
* </ul>
* <p>
* The NRLMSISE-00 model was developed by Mike Picone, Alan Hedin, and Doug Drob.<br>
* They also wrote a NRLMSISE-00 distribution package in FORTRAN available at:<br>
* ftp://hanna.ccmc.gsfc.nasa.gov/pub/modelweb/atmospheric/msis/nrlmsise00/<br>
* <br>
* Dominik Brodowski implemented a C version of the NRLMSISE-00 model available at:<br>
* http://www.brodo.de/space/nrlmsise/index.html
* <p>
* Instances of this class are immutable.
