Constructor Detail

JSightInfo

public JSightInfo()

Constructs a new sight info for the specified star at the given latitude. After construction, the layout is done with the init() method.

Parameters:

star - A star with at least right ascension and declination, both in degrees.

latitude - The observer's latitude, in degrees.

Method Detail

setLatitude

public void setLatitude(double lat)

Sets the latitude of the sight info. Updates the relevant labels.

setObject

public void setObject(StarDescription star)

Sets the object of the sight info. Updates the relevant labels.

setHeliacalSunHeight

public void setHeliacalSunHeight(double h)

Sets the heliacal sun height on rise and set.

setHeliacalHeight

public void setHeliacalHeight(double htarget)

Sets the heliacal target height on rise and set.

update

private void update()

Updates relevant labels.

init

public void init()

Lays out the panel. Setting position and latitude will only affect displayed values.
