public class FlatMaximumTime
extends AbstractTargetValue
implements ExposureTimeMeasuring

The maximum exposure time allowed for flats is a filter function, because it basically defines when too much star light is visible in the flat. There is an upper cut that is related to the time scale of twilight darkening, as it is not useful to expose for an hour, if it is getting too dark too fast.

Construction of the flat exposure time calculator.

Method Detail

init

public void init()
          throws InitException

On init, we create the table for calculating the times.

Specified by:

init in interface Initializable

Overrides:

init in class AbstractParameter

registerTarget

public void registerTarget(TargetDefinition td)

We register the target. Grabs the the target filter and grabs the current time-stamp to allow proper identification of the fits moments.

Specified by:

getValue

public Number getValue()

We get the estimated flat exposure time.

Specified by:

getValue in interface Value

setValue

public Number setValue(Number v)

We get the estimated flat exposure time.

Specified by:

setValue in interface Value

getForTarget

public Number getForTarget(TargetDefinition td)

If queried with a target, we always ignore the fits moments, as these cannot be valid.

Specified by:

getForTarget in interface TargetDependingParameter

Specified by:

getForTarget in interface TargetDependingValue
