Package | Description |
---|---|
net.grelf |
This package contains general-purpose Java classes: non-astronomical and
not specific to GRIP.
|
net.grelf.astro |
This package contains Java classes for astronomical applications.
|
net.grelf.grip |
This package contains the Java classes which are specific to the image
processing application GRIP.
GRIP is available as a free download from www.grelf.net - please always quote this URL in connection with GRIP. Version: 18.1.24 |
net.grelf.image |
This package contains Java classes defining and processing images.

net.grelf.meteor |
Class and Description |
---|
Angle
In java.lang.(Strict)Math you have to keep track of whether an angle is in
degrees or radians when you use trigonometrical functions; the present
class knows what to do, so you can forget about it! This should reduce
the potential for errors of the degrees/radians kind.
Rationale A continual refrain in Jean Meeus' excellent series of books on astronomical computation is the risk of errors due to the fact that angles are usually given in degrees but trigonometry requires radians. |
Angle.Units |
Complex
Complex numbers and operations upon them.
|
FileFilterExtra
Support class for FileIO.
|
FileIOImageFilter
Support class for FileIO.
|
Fitter
Fits data to particular curves.
|
Length
A measured length, with units.
|
Length.Units |
Line
Defining a geometrical line y = m.x + c, where m is the gradient and
c is the y-intercept.
|
LineSegment
Segment of a geometrical line, defined by two end points.
|
Maths.Statistics
Just a record to hold public values.
|
MeasuredValue
Record to hold a measured value x, its standard error S and its units, so
it can be stated as x +/- S units.
|
MixedUnitsException
Thrown if there is an attempt to combine arithmetically 2 quantities with
different units.
|
NoUnits
Dummy units for any MeasuredValue which has no units.
|
PointFloat
A 2D geometrical point with coordinates of type float.
|
Stack
A simple last-in-first-out (LIFO) stack, to a better OO design than Sun's
one: it only exposes the behaviour that a stack should have.
|
Statistics
Record to hold a set of measurements of a distribution.
|
TimeInterval
This class describes the start and end times of an image exposure.
|
Triangle
Experimental, in development.
|
Triangle.CycleSense |
Units
Type definer
|
VectorFloat
Objects of this class describe the vector connecting two detected objects
(Blobs).

AbstractDialogue
Provide some methods for GRIP dialogues to inherit: they should extend this
rather than JDialog.

InadequateDataException
May be thrown if an operation cannot be carried out because the data are
not suitable.
|
MeasuredValue

it can be stated as x +/- S units.
|
TimeInterval
This class describes the start and end times of an image exposure.
