Detailed Description

Processor to calculate Gaus profile parameters for stars on the CCD frame.

Processor calculates Gaus profile parameters for stars found on CCD images from the input collection. For each star found in the image (after background subtraction is applied) following parameters of its profile are calculated from the selected pixels: RMS in X, RMS in Y, XY-correlation, FWHM, Elongation and orientation. Median of the obtained parameter value is calculated in given number of frame sectors and the resulting map is stored in the output table. It can then be used to calculating Gauss kernel for given image.

Input: Processor reads images from the Gloria data collection

Parameters

ImageCollectionName - Name of the collection containing input images

Algorithm parameters: User can modify processor performance by specify number of sectors on the analysed frame. Moreover user can choose, whether want only brigher stars or also darker by defining parameter to distinguish the stars from the sky (in units of noise level)

Parameters

BackgroundSampling	- Background level calculation for the whole image can be sped up by considering only 1/BackgroundSampling of pixels.
BackgroundFrameDivision	- Background for the image is calculated for BackgroundFrameDivision x BackgroundFrameDivision subimages and then interpolated between them.
FrameDivision	- Shape parameter map is calculated for FrameDivision x FrameDivision subimages.
InterpolationOrder	- polinomial order used to interpolate between centers of subframes when calculating background values on the image
pixThreshold	- signal threshold for the pixel to be considered as a star maximum (if higher than all its neighbours; in units of noise level)
medianThreshold	- cut on the signal median of all pixels used for star shape calculation (in units of noise level). New pixels are added to the star until this threshold is met.
MaxPixelValue	- signal threshold for the saturated pixels used to eliminate saturated stars and shape analysis (in value of pixel)

Output: Object lists are stored in the output collection

Parameters

OutputCollectionName	- Name of the collection where parameter map will be stored
PermanentCollection	- Flag output table collection, as permanent, not deleted after loop is finished (default is false)

void luiza::CalculateGausPSF::check ( GloriaDataContainer * )

virtual

Called for every loop - right after processData() call.

Can be used to check processing and/or produce check plots.

Reimplemented from luiza::Processor.

void luiza::CalculateGausPSF::end ( )

virtual

Called after data processing for clean up.

Reimplemented from luiza::Processor.

void luiza::CalculateGausPSF::init ( )

virtual

Called at the begin of the job before anything is read. Use to initialize the processor, e.g. book histograms.

Reimplemented from luiza::Processor.

virtual Processor* luiza::CalculateGausPSF::newProcessor ( )

inlinevirtual

Return a new instance of the processor.

Has to be implemented by subclasses.

Implements luiza::Processor.

void luiza::CalculateGausPSF::printEndMessage ( ) const

protected

Test method for const.

void luiza::CalculateGausPSF::processData ( GloriaDataContainer * data )

virtual

Called for every data loop

Reimplemented from luiza::Processor.

void luiza::CalculateGausPSF::startAnalysis ( GloriaDataContainer * )

virtual

Called before first data processing loop.

Can be used to initialize data collections required for analysis, eg. define permanent collections, or fill them with external data (from file, database or net). It is possible as GloriaDataContainer is already defined, contrary to init().

Reimplemented from luiza::Processor.

int luiza::CalculateGausPSF::_backgroundFrameDivision

protected

Frame division for background calculation.

Background is calculated for BackgroundFrameDivision x BackgroundFrameDivision subimages and then interpolated between them

int luiza::CalculateGausPSF::_backgroundSampling

protected

Background sampling factor.

Parameter used to speed up background level calculation. Only every BackgroundSampling pixel is used.

int luiza::CalculateGausPSF::_frameDivision

protected

Frame division for shape map calculation.

Shape parameter maps are calculated for FrameDivision x FrameDivision subimages

bool luiza::CalculateGausPSF::_useTelescopeParameters

protected

Use network configuration file to update processor parameters.

When true, network configuration file is checked for each analysed image and processor parameters are changed if default parameter values are defined for given instrument/telescope.
