IMPSTAR (IMage Processing, STatistics And Regions of interest) is used for further analysis of 2-Dimensional images. It can be used for signal-to-noise and other statistical analysis, for integral calculation and image smoothing, or for adding and subtracting images. IMPSTAR can load files of 2D datasets in DAT, Bruker or CSV format and images in JPEG or TIFF format. Data can be saved either in DAT or Bruker format. The main program is Impstar.pro.
