Class AbstractFieldOfView

java.lang.Object

util.PropertyContainer

stella.acquire.AbstractFieldOfView

All Implemented Interfaces:

Cloneable, FieldOfViewProviding, Pointing, PropertySupplying

Direct Known Subclasses:

AuxiliaryFieldOfView, CentralStarFieldOfView

public abstract class AbstractFieldOfView
extends PropertyContainer
implements FieldOfViewProviding

The abstract field of view provides setters for the catalog stars, the acquire center and a possible dither shift. It also defines methods in FieldOfViewProviding with the exception of methods that return a acquisition star.

Field Detail

catalog

protected List<Star> catalog

All stars submitted to the acquire unit in a FindAdapter.

center

protected Vector2D center

The acquisition center ra and de, degrees. .

dither

protected Vector2D dither

The dithering offset, degrees.

Constructor Detail

AbstractFieldOfView

protected AbstractFieldOfView(Map<String,String> props)

Parameters:

props -

Method Detail

setFindList

protected void setFindList(List<Star> fov)

Sets the list of stars following a FindAdapter or FindAuxiliary command. The stars must be propagated with their proper motion to match the current epoch before they are sent. The field of view stored in the catalog is sorted to magnitude.

Parameters:

fov - Stars must have ra, de, and mag, optionally B-V

setRaDePointing

protected void setRaDePointing(double ra,
                               double de)

Sets the acquisition center following a AcquireAdapter or AcquireAuxiliary command. Clears dither

Parameters:

ra - Right ascension of acquisition center, degrees.

de - Declination of acquisition center, degrees.

setDitherOffset

protected void setDitherOffset(double dradeg,
                               double ddedeg)

Sets the dither offset following a DitherAuxiliary.

Parameters:

dradeg - Dither offset in degrees for right ascension.

ddedeg - Dither offset in degrees for declination.

reset

public void reset()

Marks the field-of view and center invalid, clears dither.

getRaDeCenter

public Vector2D getRaDeCenter()

Description copied from interface: Pointing

Returns the right ascension and declination of the requested acquisition. Both angles in degrees.

Specified by:

getRaDeCenter in interface Pointing

Returns:

getFieldOfView

public List<Star> getFieldOfView()

Description copied from interface: FieldOfViewProviding

Returns the entire field of view known.

Specified by:

getFieldOfView in interface FieldOfViewProviding

getFieldOfViewAround

public List<Star> getFieldOfViewAround(Star center,
                                       double degs)

Description copied from interface: FieldOfViewProviding

Returns a field-of-view centered around a certain star. The radius of the field is in degrees.

Specified by:

getFieldOfViewAround in interface FieldOfViewProviding

defaultGuidingStar

public static Star defaultGuidingStar(List<Star> def,
                                      double racenter,
                                      double decenter,
                                      float minmag)

Default guiding star, above defined threshold.
