		double	axis2_low_deg,
		double	axis2_up_deg
	)

constructor

Author: Matthias Schartner

Member Function Documentation

bool CableWrap_AzEl::anglesInside ( const PointingVector & p ) const

overridevirtualnoexcept

checks if this pointing vectors azimuth and elevation are inside the axis limits

Author: Matthias Schartner

Parameters

p	pointing vector which should be tested

Returns: true if inside, otherwise false

Implements VieVS::AbstractCableWrap.

Here is the call graph for this function:

AbstractCableWrap::CableWrapFlag CableWrap_AzEl::cableWrapFlag ( double unaz ) const

overridevirtualnoexcept

cable wrap section based on unwrapped azimuth

Author: Matthias Schartner

Parameters

unaz	unwrapped azimuth in radians

Returns: cable wrap section

Implements VieVS::AbstractCableWrap.

Here is the call graph for this function:

std::pair< std::string, std::string > CableWrap_AzEl::getMotions ( ) const

overridevirtualnoexcept

antenna motion names in .vex format

Author: Matthias Schartner

Returns: antenna motion name for first and second axis (e.g.: {"az", "el"})

Implements VieVS::AbstractCableWrap.

bool CableWrap_AzEl::unwrapAzInSection	(	PointingVector &	pv,
		char	section
	)		const

overridevirtualnoexcept

unwraps the current azimuth of pointing vector in specific cable wrap section

Author: Matthias Schartner

The azimuth of one pointing vector is first calculated in the range between [-pi,pi]. This function adds an factor of 2*pi so that the azimuth is inside the cable wrap section limits.

This function takes cable wrap section in sked format.

'C': clock wise
'-': neutral
'W': counter clock wise

Parameters

pv	pointing vector whose azimuth should be unwrapped
section	cable wrap section in sked format

Returns: true if unwrapping was possible, otherwise false

Implements VieVS::AbstractCableWrap.

Here is the call graph for this function:

void CableWrap_AzEl::unwrapAzNearAz	(	PointingVector &	new_pointingVector,
		double	az_old
	)		const

overridevirtualnoexcept

unwraps the current azimuth of pointing vector

Author: Matthias Schartner

The azimuth of one pointing vector is first calculated in the range between [-pi,pi]. This function adds an factor of 2*pi so that the azimuth is inside the axis limits. If there are possible ambiguities, for example if the azimuth axis range is bigger than 360 degrees, the value, which is closest to the second input parameter value (az_old) is used.
