Member Function Documentation

template<class precision> void Arroyo::pixel_amp_array< precision >::amp_clip (  const double &  min, const double &  max )

Amp clip the pixel_amp_array

template<class precision> double Arroyo::pixel_amp_array< precision >::aperture_photometry (  double  x, double  y, double  inner_radius, double  outer_radius )  const

Function to perform aperture photometry All arguments in pixels

template<class precision> std::vector< float > Arroyo::pixel_amp_array< precision >::azav (  int  xcenter, int  ycenter )

Function to perform an azimuthal average around a central point

template<class T> double Arroyo::pixel_amp_array< T >::fit (  int  npsfs, const pixel_amp_array< precision > &  psf, vector< double > &  differential_amplitudes, vector< vector< double > > &  relative_offsets, pixel_amp_array< precision > &  fitted_model, pixel_amp_array< precision > &  fit_residual )  const

Function to model this data as npsfs shifted and scaled copies of the array psf. The best fitting model is returned in fitted_psf, and the residuals are returned in fit_residual. Relative offsets are measured in pixels. Arrays must be the same dimension.

template<class T> double Arroyo::pixel_amp_array< T >::fit (  const pixel_amp_array< precision > &  psf, double &  differential_amplitude, double &  offset, bool  fit_for_offset, vector< double > &  relative_offsets, pixel_amp_array< precision > &  fitted_psf, pixel_amp_array< precision > &  fit_residual, pixel_amp_array< precision > &  orig )  const

Function to model this data as a single shifted and scaled copy of the array psf, plus a DC offset. The best fitting model is returned in fitted_psf, and the residuals are returned in fit_residual. Relative offsets are measured in pixels. Arrays must be the same dimension.

template<class T> double Arroyo::pixel_amp_array< T >::fit (  const pixel_amp_array< precision > &  psf, double &  differential_amplitude, vector< double > &  relative_offsets, pixel_amp_array< precision > &  fitted_psf, pixel_amp_array< precision > &  fit_residual, pixel_amp_array< precision > &  orig )  const

Function to model this data as a single shifted and scaled copy of the array psf. The best fitting model is returned in fitted_psf, and the residuals are returned in fit_residual. Relative offsets are measured in pixels. Arrays must be the same dimension.

template<class precision> template<class U> void Arroyo::pixel_amp_array< precision >::flag_outliers (  const pixel_amp_array< U > &  pixamparr, const double &  threshold )

This function compares this pixel_amp_array to the argument and deletes points in this instance for which the difference between the two instances is greater than sigma_clip*rms and for which the point in this instance is greater than sigma_clip*rms

template<class precision> void Arroyo::pixel_amp_array< precision >::interpolate (   )
