A set of functions for obtaining positional parameters and magnitude difference between components of binary and multiple stellar systems from series of speckle images.
R package specklestar is a set of C++ and R functions used in the Group of high-resolution methods in astronomy of the Special Astrophysical Observatory of the Russian Academy of Science for reduction of speckle data obtained from BTA 6-m telescope. Input data are series of 512 x 512 (x 2 bytes) speckle images 🌠
For reduction of speckle images of binary and multiple stars we use algorithm described in paper "Differential photometry of speckle-interferometric binary and multiple stars" Pluzhnik E.A., Astronomy and Astrophysics, v.431, p.587-596 (2005).
First install fftw library. Then
# From CRAN install.packages(c("Rcpp", "specklestar"))
# Development version from GitHub install.packages("devtools") devtools::install_github("drastega/specklestar", build_vignettes = TRUE) # Recommended image viewer devtools::install_github("yapus/imageviewer")
