Detailed Description

Convert between undistorted focal plane and ground coordinates.

This base class is used to convert between undistorted focal plane coordinates (x/y) in millimeters and ground coordinates lat/lon. This class handles the case of framing cameras.

◆ LookDirection()

void Isis::VimsSkyMap::LookDirection ( double v[3] )

private

Determines the look direction in the camera coordinate system.

Parameters

[out] v Look direction vector in camera coordinates

This method will compute the look direction vector in the camera coordinate system. This code was converted from Rick McCloskey's point_tbl c code.

History:: 2008-01-03 Tracie Sucharski - Converted Rick'scode rather than using the unitVector files from Rick.

History:: 2013-11-18 Tracie Sucharski - Added this method to VimsSkyMap,so that old unitVector files are no longer needed.

virtual

Compute ground position from focal plane coordinate.

This method will compute the ground position given an undistorted focal plane coordinate. Note that the latitude/longitude value can be obtained from the camera class passed into the constructor.

Parameters

uy	distorted focal plane y in millimeters
uz	distorted focal plane z in millimeters

Returns: conversion was successful

virtual

Sets the sky position to the given ra and dec.

Parameters

ra	the right ascension
dec	the declination

Returns: set sky was successful
