Method Detail

getChannelID

public int getChannelID(Hep3Vector point)

Converts a point in local sensor coordinates to channel ID. Returns -1 if the point is outside of sensor sensitive area.

Specified by:

getChannelID in interface SensorType

getChannelPosition

public Hep3Vector getChannelPosition(int channelID)

Returns position of the center of a given channel, in local sensor coordinates.

Specified by:

getChannelPosition in interface SensorType

getMaxChannelID

public int getMaxChannelID()

Returns maximum channel ID on this sensor.

Specified by:

getMaxChannelID in interface SensorType

isValidChannelID

public boolean isValidChannelID(int channelID)

Returns true if channel with this ID exists on this sensor.

Specified by:

isValidChannelID in interface SensorType

getChannelDimensions

public Hep3Vector getChannelDimensions(int channelID)

Returns dimensions of a given channel along U, V, W.

Specified by:

getChannelDimensions in interface SensorType

getHitDimension

public int getHitDimension()

Returns the dimension of a measurement by this type of sensor (1 since WedgeSideParallel is always tiled with strips).

Specified by:

getHitDimension in interface SensorType

getNeighbor

public int getNeighbor(int channelID,
              int shiftU,
              int shiftV)

Returns ID of a channel obtained by shifting the given channel by the given number of channels in the given direction along the local reference frame axis. Returns -1 if shifting puts the point outside of the sensor boundaries. Throws IllegalArgumentException if this type of sensor does not have a concept of a neighbor in the given direction.

Specified by:

getNeighbor in interface SensorType

Parameters:

channelID - ID of the original channel

shiftV - move in V direction by shiftV channels

shiftU - move in U direction by shiftU channels

getNeighbors

public List<Integer> getNeighbors(int channelID)

Returns array of IDs of all immediate neighbor channels.

Specified by:

getNeighbors in interface SensorType

getCorners

public double[][] getCorners()

Returns an array of (U,V) coordinates of corners of the sensor. Useful for event display. The dimensions of the returned array are [4][2].
