Detailed Description
This structure stores all relevant data of a gaussian signal.Gaussians are signals whose power should increase and then decrease with a bell-shaped curve in time. The idea behind this is that Signals from a distant transmitter should get stronger and then weaker as the telescope's focal point moves across that area of the sky. The gaussian test is only applied for frequency resolutions greater than or equal to 0.59 Hz. Since noise can sometimes randomly simulate a gaussian, the SETI@home client only returns gaussians stronger than 3.2 times the average noise level with a fit (chisq) less than 8.8.

|
|
The gaussian power. This value tells us how strong the signal is relative to noise. Definition at line 72 of file setidefs.h. Referenced by SetiContainer::initWUScore, and SetiContainer::scanGaussianData. |
|
|
The score of the gaussian. This value is determined by calculating (power/chisq). Definition at line 75 of file setidefs.h. Referenced by SetiContainer::initWUScore, and SetiContainer::scanGaussianData. |
|
|
An integer value representing the gaussian.
Definition at line 77 of file setidefs.h. Referenced by SetiContainer::initWUScore, and SetiContainer::scanGaussianData. |
|
|
A fit value indicating how well a rising and falling signal fits an ideal gaussian (bell curve) profile. A lower fit value means a better fit. Definition at line 81 of file setidefs.h. Referenced by SetiContainer::initWUScore, and SetiContainer::scanGaussianData. |
|
|
The fitted mean value.
Definition at line 83 of file setidefs.h. Referenced by SetiContainer::initWUScore, and SetiContainer::scanGaussianData. |
|
|
Sigma represents the width of the gaussian.
Definition at line 85 of file setidefs.h. Referenced by SetiContainer::initWUScore, and SetiContainer::scanGaussianData. |
|
|
The fft index value.
Definition at line 87 of file setidefs.h. Referenced by SetiContainer::initWUScore, and SetiContainer::scanGaussianData. |
|
|
The fft length (number of data points).
Definition at line 89 of file setidefs.h. Referenced by SetiContainer::initWUScore, and SetiContainer::scanGaussianData. |
|
|
The chirp rate at which this gaussian was found. See StateFileData for a detailed explanation. Definition at line 92 of file setidefs.h. Referenced by SetiContainer::initWUScore, and SetiContainer::scanGaussianData. |
|
|
This array stores the gaussian shape.
Definition at line 94 of file setidefs.h. Referenced by SetiContainer::initWUScore, and SetiContainer::scanGaussianGraphData. |
|
|
The amount of data values in the array (should be always 64 for gaussians).
Definition at line 97 of file setidefs.h. Referenced by SetiContainer::initWUScore, and SetiContainer::scanGaussianGraphData. |
|
|
The sky position (right ascension).
Definition at line 99 of file setidefs.h. Referenced by SetiContainer::initWUScore. |
|
|
The sky position (declination).
Definition at line 101 of file setidefs.h. Referenced by SetiContainer::initWUScore. |
|
|
The frequency at which the signal was found.
Definition at line 103 of file setidefs.h. Referenced by SetiContainer::initWUScore. |
|
|
The name of work unit in which the gaussian was found.
