stella.command.OnSkyOffsetTelescope

All Implemented Interfaces:

Serializable, TelescopeCommand

Direct Known Subclasses:

EncoderOffsetTelescope, TotalEncoderOffsetTelescope

public class OnSkyOffsetTelescope
extends OffsetTelescope

The command sent from an acquisition unit to the telescope, so to get to true azimuth encoder offsets, the measured offset has to be divided by cos(h).

Constructor Detail

OnSkyOffsetTelescope

public OnSkyOffsetTelescope(Object src)

Constructs a abort adapter telescope, grabbing the type from the class name and setting the command time to the current system time.

OnSkyOffsetTelescope

public OnSkyOffsetTelescope(Object src,
                            String id,
                            long time)

Constructs a new offset telescope command. The command only gets valid when either its parseLine(java.lang.String[]) or the OffsetTelescope.setOffset(double, double) method are called.
To mark both offsets invalid, NaN is assigned to them.

Method Detail

getLine

public String[] getLine()

Returns the command line of the move telescope command.

Overrides:

getLine in class OffsetTelescope

Returns:

An array containing all command lines.

parseLine

public boolean parseLine(String[] all)

Parse the command line into ra and dec of the move command.

Overrides:

parseLine in class OffsetTelescope

Returns:

True, if parsing was successful.

setHeight

public void setHeight(double h)

Sets the height of the telescope, if currently known.

getHeight

public double getHeight()

Return the height of the telescope.

setAzimuth

public void setAzimuth(double a)

Sets the height of the telescope, if currently known.

getAzimuth

public double getAzimuth()

Return the height of the telescope.
