Description

Class Summary

AstroGridGateway	This singleton class contains methods for accessing the online AstroGrid (see www.astrogrid.org).
Dec	Representation of declination (celestial latitude).
Epoch	Represent astronomical epochs, such as B1950.0 or J2010.0.
Hipparcos	For loading data from the Hipparcos data file hip_main.dat for use in class StarChart.
JulianDate	This class holds a Julian date/time to an accuracy of 1ms.
JulianDateDialogue	Dialogue for user to convert between Gregorian calendar and JD.
Magnitude	Type representing astronomical magnitude.
MagnitudeBands	Holds assignment of known magnitude bands of reference stars to image channels for magnitude estimation.
MagnitudeChart	This displays a clone of the ImFrame used for magnitude estimation, with the measured stars marked in it.
MagnitudeGraph	A GUI component for displaying a graph of blob brightnesses against known stellar magnitudes, doing a least-squares fit and then estimating unknown magnitudes from brightnesses.
MagnitudeTable	A GUI component for displaying a table of blob areas, brightnesses and stellar magnitudes, for all blobs for which the user has entered an identifier via the blob menu.
ProperMotion	Representing the proper motion of a star, in RA and Dec, with units (always) of arcsec per year.
RA	Representation of Right Ascension (celestial longitude).
SimbadGateway	Access Simbad service at CDS directly over HTTP (not via AstroGrid) to get data for star(s).
SkyPoint	Representing a celestial position by equatorial coordinates (RA and Dec) for a given Epoch.
SkyPointDialogue	Presents a user interface for defining a net.grelf.astro.SkyPoint, changing its epoch, etc.
SkyPointPane	For entering coordinates of a SkyPoint (or obtaining from Simbad) and transforming them for precession.
SkyVector	Represents a vector on the celestial sphere, eg between two SkyPoints.
Star	A star can have several ids, from different catalogues.
StarChart	A square of star chart, centred at user-provided coordinates and of user-chosen size, displayed in an ImFrame.
StarChart.StarChartDialogue	Enable users to set coordinates and other parameters for creating a star chart.
StarChartLoader	Base for classes loading data for StarChart.
Tycho	For loading data from the Tycho data file tyc_main.dat for use in class StarChart.

Enum Summary

BodyKind	Identifies kinds of celestial objects.
StarChartSource	For defining the data source to be used when creating a star chart.
Variability	Categorise variable stars, compatible with VarFlag in the Hipparcos data set.
