| Class and Description |
|---|
| AstroGridGateway
This singleton class contains methods for accessing the online AstroGrid
(see www.astrogrid.org).
|
| BodyKind
Identifies kinds of celestial objects.
|
| Dec
Representation of declination (celestial latitude).
|
| Epoch
Represent astronomical epochs, such as B1950.0 or J2010.0.
|
| JulianDate
This class holds a Julian date/time to an accuracy of 1ms.
|
| Magnitude
Type representing astronomical magnitude.
|
| MagnitudeBands
Holds assignment of known magnitude bands of reference stars to image
channels for magnitude estimation.
|
| 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.
|
| 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.
|
| StarChartLoader
Base for classes loading data for StarChart.
|
| StarChartSource
For defining the data source to be used when creating a star chart.
|
| Topocentre
Representing locations on the Earth's surface, objects of this class are
responsible for transforming from geocentric to topocentric coordinates.
|
| Variability
Categorise variable stars, compatible with VarFlag in the Hipparcos data set.
