![]() ![]() Two martini-glass hot tubs flank the pool. We like that there's a wade-in area - with lounge chairs in the water - so you can cool off without taking the plunge. ![]() In addition to any model-specific policy, please refer to the General Publication Policy.Celebrity Apex has a lovely, long main pool with a number of padded lounge chairs surrounding it.

Magnetic field strength, azimuth and inclination, field line traces. The program BILCAL produces tables of the geomagnetic field strength, vector components (B-abs., B-north, B-east, B-down, declination, inclination), equatorial/minimum field strength (B0), dipole moment, and L-value in latitude, longitude (geodetic), altitude, or year (decimal). The IGRF subroutines were developed by A. His use of inverse cartesian co- ordinates simplifies the computation. ![]() Kluge at the European Space Operations Center (ESOC). The CCMC version uses the subroutines FELDG (magnetic field vector) and SHELLG (L shell) developed by G. In combination with the IGRF coefficient sets different subroutines have been used to determine the components of the magnetic field vector and the L-value at a given location. The 13th generation includes definite coefficients sets through 2015, preliminary sets for 2020 and extrapolations through 2025. The 12th generation of the IGRF model (IGRF12) consists of definitive coefficients sets through 2010, preliminary sets for 2015 and extrapolations from 2015 to 2020. The 11th generation of the IGRF model (IGRF11) consists of definitive coefficients sets for through 2005, preliminary sets for 2010 and extrapolations from 2010 to 2015. The 10th generation of the IGRF model (IGRF10) consists of definitive coefficients sets for 1945 through 2000, preliminary sets for 2005, and secular variations extrapolating from 2005 to 2010. IGRF#S.DAT provides the first time derivatives of the coefficients for extrapolation into the future. There are definitive coefficient sets (DGRF#.DAT) for which no further revisions are anticipated and IGRF#.DAT and IGRF#S.DAT for which future updates are expected. The IGRF model consists of sets of coefficients for a global representation of the Earth magnetic field for the years 1945, 1950, 1955, etc. ![]() The IGRF model coefficients are based on all available data sources including geomagnetic measurements from observatories, ships, aircrafts and satellites. The model employs the usual spherical harmonics expansion of the scalar potential in geocentric coordinates. The IGRF model represents the main (core) field without external sources. The International Geomagnetic Reference Field (IGRF) model is the empirical representation of the Earth's magnetic field recommended for scientific use by a special Working Group of the International Association of Geomagnetism and Aeronomy (IAGA). ![]()
