public class FlatPointing
extends AbstractParameter
implements ParameterDepending, CommandLineProviding

Provides the nominal best sky-flat pointing position, as reported in PASP 108, 944 (1996). This is in anti-solar azimuth, a 10 deg away from zenith.

As learned later, Pilar can only track positions if they are set using ra/de. Thus we have to convert the final az,h=80 further to ra/de. No comment.

Constructor Summary

Defaults the name.

Method Summary

Object	get() We get the command line.
String	getCommandLine() The command line is null if the solar azimuth was not registered, otherwise it is the nautic azimuth folloed by blank, followed by the pointing altitude for the flat field exposure.
void	registerParameter(Parameter az) We need the azimuth of the sun.
Object	set(Object to) This is not allowed.

Constant Field Values

sun

private SolAzimuth sun

The parameter that delivers current solar azimuth.

theta

private SiderealTime theta

To get from the hour angle to ra, we also need sidereal time.

phi

private Latitude phi

And the latitude.

Constructor Detail

FlatPointing

public FlatPointing(Map<String,String> prop)

Defaults the name.

Method Detail

registerParameter

public void registerParameter(Parameter az)

We need the azimuth of the sun. For further conversion to ra/de, we need the latitude and sidereal time.

Specified by:

registerParameter in interface ParameterDepending

get

public Object get()

We get the command line.

Specified by:

get in interface Parameter

set

public Object set(Object to)

This is not allowed.

Specified by:

set in interface Parameter

Returns:

The previous value of this parameter.

getCommandLine

public String getCommandLine()

The command line is null if the solar azimuth was not registered, otherwise it is the nautic azimuth folloed by blank, followed by the pointing altitude for the flat field exposure.

Specified by:

getCommandLine in interface CommandLineProviding
