Thetype exposes the following members.
Returns the topocentric azimuth angle of the target
Returns the Declination in apparent co-ordinates
Returns the Declination in J2000 co-ordinates
Returns the Declination in topocentric co-ordinates
Returns the topocentric elevation of the target
Sets or returns the Julian date on the Terrestrial Time timescale for which the transform will be made
Sets or returns the Julian date on the UTC timescale for which the transform will be made
Returns the Right Ascension in apparent co-ordinates
Returns the Right Ascension in J2000 co-ordinates
Returns the Right Ascension in topocentric co-ordinates
Gets or sets a flag indicating whether refraction is calculated for topocentric co-ordinates
Gets or sets the site elevation above sea level
Gets or sets the site latitude
Gets or sets the site longitude
Gets or sets the site ambient temperature
Cleans up resources used by the Transform component
Causes the transform component to recalculate values derived from the last Set command
Sets the known apparent Right Ascension and Declination coordinates that are to be transformed
Sets the topocentric azimuth and elevation
Sets the known J2000 Right Ascension and Declination coordinates that are to be transformed
Sets the known topocentric Right Ascension and Declination coordinates that are to be transformed
The component can be reused simply by setting new co-ordinates with a Set command, there is no need to create a new component each time a transform is required.
Transforms are effected through the ASCOM NOVAS.Net engine that encapsulates the USNO NOVAS 3.1 library. The USNO NOVAS reference web page is: http://www.usno.navy.mil/USNO/astronomical-applications/software-products/novas and the NOVAS 3.1 user guide is included in the ASCOM Developer Components install.
