NAME stcube - cube statistics SYNOPSIS stcube [options] <cubes...> DESCRIPTION stcube gives basic statistics about each plane in a cube. It is used to have a quick look at what kind of data is in the cube. The display looks like : #-------------------------------------------------- # FILE stdstar_check.fits # PLANE MIN MAX MEAN MEDIAN STDEV 0001 -287 9709.33 15.0937 0.833328 228.504 #-------------------------------------------------- For each plane: MIN is the minimum value. MAX is the maximum value. MEAN is the average pixel value. MEDIAN is the median pixel value. STDEV is the standard deviation. There is one display for each FITS file given on command line. stcube accepts jokers on command line : > stcube *.fits OPTIONS -b or --badpixmap filename give a bad pixel map to take into account when comput- ing statistics on the cube. -z or --zone 'llx lly urx ury' To compute statistics only on a rectangular zone in the images. The zone is specified by indicating the coordi- nates of the lower-left and upper-right corners of the rectangle. Borders are inclusive. The coordinate sys- tem is the one used by FITS, namely that the lower left pixel in the image is labelled (1,1), x-axis increasing from left to right, y-axis increasing from bottom to top. -s or --stdev <name> To compute a standard deviation frame (only), with name <name>. This mode of stcube accepts only one input file name, which should correspond to the name of a 3d FITS file or a valid ASCII list (i.e. a data cube). The input cube is processed to obtain a frame that is giv- ing the standard deviation of all pixels along time. If several input names are provided, only the first one will be taken into account. EXAMPLES To compute the standard deviation frame named 'stdev.fits' from a cube named 'cube.fits', you would use: > stcube --stdev stdev.fits cube.fits To compute statistics on the lower left quadrant only of a 256x256 image, you would use: > stcube --zone '1 1 128 128' image.fits
