Detailed Description

The EphemerisTable class is an Alma table.

Role

Generated from model's revision "-1", branch ""

Attributes of Ephemeris
Name	Type	Expected shape	Comment
Key
timeInterval	ArrayTimeInterval		interval of time during which the data are relevant.
ephemerisId	int		identifies a collection of rows in the table.
Value (Mandatory)
observerLocation	std::vector<double >	3	a triple of double precision values defining the observer location. This triple contains in that order the longitude, the latitude and the altitude of the observer : the longitude is expressed in radian. An east (resp. west) longitude is denoted as a positive (resp. negative) quantity. the latitude is expressed in radian. A north (resp. south) latitude is denoted as a positive (resp. negative) quantity. the altitude is expressed in meter. It's the altitude above the reference ellipsoid. A triple with all its elements equal to 0.0 will mean that a geocentric coordinate system is in use instead of a topocentric one.
equinoxEquator	double		epoch at which equator and equinox were calculated for ephemeris. Expresses a year as a decimal value (J2000 would be represented as 2000.0).
numPolyDir (numPolyDir)	int		the number of coefficients of the polynomial stored in phaseDir. It has to be $\ge 1$ .
dir	std::vector<std::vector<double > >	numPolyDir, 2	the ephemeris direction expressed in radian. The nominal entry in the phaseDir, delayDir, or ReferenceDir in the Field table serves as additional offset to the direction described by "dir". The actual direction is obtained by composition, e.g. actual phase direction = [phasDir value from Field table] + [dir]. The direction described by dir is the result of the sum $dir_{0,i} + dir_{1,i}dt + dir_{2,i}dt^2 + ... + dir_{numPolyDir-1,i}*dt^{numPolyDir-1}, \forall i \in \{0,1\}$ where $dt = t - timeOrigin$
numPolyDist (numPolyDist)	int		the number of coefficients of the polynomial stored in distance. It has to be $\ge 1$ .
distance	std::vector<double >	numPolyDist	the coefficiens of the polynomial used to calculate the distance, expressed in meter, to the object from the position of the antenna along the given direction. This distance is the result of the sum : $distance_0 + distance_1dt + distance_2dt^2 + ... + distance_{numPolyDist-1}*dt^{numPolyDist-1}$ where $dt = t - timeOrigin$ .
timeOrigin	ArrayTime		the time origin used in the evaluation of the polynomial expressions.
origin	std::string		the origin of the ephemeris information.
Value (Optional)
numPolyRadVel(numPolyRadVel)	int		the number of coefficients of the polynomial stored in radVel . It has to be $\ge 1$ .
radVel	std::vector<double >	numPolyRadVel	the coefficients of a polynomial expressing a radial velocity as a function of the time expressed in m/s. The time origin used to tabulate the polynomial is stored in timeOrigin.

Constructor & Destructor Documentation

virtual asdm::EphemerisTable::~EphemerisTable ( )

virtual

asdm::EphemerisTable::EphemerisTable ( ASDM & container )

private

This constructor is private because only the container can create tables. All tables must know the container to which they belong.

Parameters

====> Append a row to its table.

Add a row.

Parameters

x	a pointer to the EphemerisRow to be added.

Returns: a pointer to a EphemerisRow. If the table contains a EphemerisRow whose attributes (key and mandatory values) are equal to x ones then returns a pointer on that EphemerisRow, otherwise returns x.

Exceptions

DuplicateKey { thrown when the table contains a EphemerisRow with a key equal to the x one but having and a value section different from x one }

Parameters

e	An entity.
