Usage

get_ppp_dead(detector)

Arguments

detector

Detector object

ppp of dead pixels

Examples

# Create a detector
detector_pilatus <- create_detector("Pilatus")
# Load a pixel matrix
file_path <-  system.file("extdata", "Pilatus", "badpixel_mask.tif",
                         package ="detectorchecker")
detector_pilatus <- load_pix_matrix(
 detector = detector_pilatus, file_path = file_path)
# Create a point pattern dataset from the detector
dead_ppp <- get_ppp_dead(detector_pilatus)
