Method Detail

blowup

public static final MImageHDU blowup(MImageHDU src,
                                     int xblow,
                                     int yblow)
                              throws BasicFitsException

Takes the binned source and unbinns the image artificially by blowing up with factors stated as integer values for x and y. Type.SUM leads to a plain copy of the ADU value to all blown up pixel, default action is to distribute evenly, with either Type AVERAGE or MEDIAN

Throws:

BasicFitsException

FitsException
