All Implemented Interfaces:

Serializable, CcdCommand, InitializerDepending, SequencerDepending, TargetDependingCommand, ParameterDepending

public class ScientificCcd
extends CommandEvent
implements CcdCommand, TargetDependingCommand, ParameterDepending, InitializerDepending, SequencerDepending

Takes a scientific exposure with the given exposure time. Only if a second argument on the command line is present and giving a fits file name the data is saved.

There are several ways to define this command with none-fixed exposure times.

Constructor Summary

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

ScientificCcd(Object src, String type, long time)
Constructs a new exposure abort command.

Method Summary

int	getExpectedAcknowledgeNumber() Returns the number of acknowledge events this command is expected to follow.
double	getExposureTime() Returns the exposure time asociated with the darktime command.
String	getFitsName() Returns the fits file asociated with the abort command.
String[]	getLine() Returns the command line of the move telescope command.
void	initWith(String init) Registers an initializer which is a sequence of filter names, separated by a colon.
boolean	isStore() Returns true, if data should be stored.
boolean	parseLine(String[] all) Parse the command line into ra and dec of the move command.
void	registerParameter(Parameter what) Registers a parameter to this command.
void	registerSequencingParameters(Map<String,Object> loop) Sets the sequence loop, but subtracts one from it as the first loop index is 1.
void	registerTargetProperties(Object setup) Calculates the command line from the properties registered.
private void	setExposureTime(double to) Sets the exposure time.
private void	setFitsName(String to) Sets the fits file name.

Field Detail

expose

private Number expose

The exposure time in seconds.

increase

private List<Double> increase

The exposure time increase in fractions.

current

private int current

Current active filter.

fitsname

private String fitsname

The fits file where to save the ccd data in. Augmented by Unique.

store

private boolean store

If false, data is not stored permanently.

parameters

private Map<String,Object> parameters

The parameter handed over.

calc

private static ExposureTime calc

The exposure time calculator.

Constructor Detail

ScientificCcd

public ScientificCcd(Object src)

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

ScientificCcd

public ScientificCcd(Object src,
                     String type,
                     long time)

Constructs a new exposure abort command. Per default no fits file is set.

Method Detail

initWith

public void initWith(String init)

Registers an initializer which is a sequence of filter names, separated by a colon.

Specified by:

initWith in interface InitializerDepending

registerParameter

public void registerParameter(Parameter what)

Registers a parameter to this command. All parameters handed over are stored in a list for later evaluation. If the parameter defines an exposure time, we query that and use that as an exposure time.

Specified by:

registerParameter in interface ParameterDepending

registerSequencingParameters

public void registerSequencingParameters(Map<String,Object> loop)

Sets the sequence loop, but subtracts one from it as the first loop index is 1.

Specified by:

registerSequencingParameters in interface SequencerDepending

registerTargetProperties

public void registerTargetProperties(Object setup)

Calculates the command line from the properties registered. Scans for the exposure time, ReservedConstants.EXPOSURETIME. Aditionally, scans for the fitsname-item, ReservedConstants.FITSNAME. If this key is present, a fits file name is generated according to FitsNameGenerator.getAbortFits(java.lang.String), otherwise the file name is set to null. A not-defined file name results in the data to be ereased.

Specified by:

registerTargetProperties in interface TargetDependingCommand

See Also:

FitsNameGenerator

getLine

public String[] getLine()

Returns the command line of the move telescope command.

Specified by:

getLine in class MessageEvent

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.

Specified by:

parseLine in class MessageEvent

Returns:

True, if parsing was successful.

getFitsName

public String getFitsName()

Returns the fits file asociated with the abort command.

getExposureTime

public double getExposureTime()

Returns the exposure time asociated with the darktime command.

isStore

public boolean isStore()

Returns true, if data should be stored.

setExposureTime

private void setExposureTime(double to)

Sets the exposure time.

setFitsName

private void setFitsName(String to)

Sets the fits file name.

getExpectedAcknowledgeNumber

public int getExpectedAcknowledgeNumber()

Returns the number of acknowledge events this command is expected to follow. Used for test case only. If not overriden, this method will return one.

Overrides:

getExpectedAcknowledgeNumber in class CommandEvent

Returns:

Three.
