Bin Menu

To create an image from a FITS Bin Table, the user needs to specify a binning factor, binning buffer size, and the binning function.

Bin Function

  • Average-- all pixel values that fall into one pixel bin are averaged.
  • Sum-- all pixel values that fall into one pixel bin are summed.
  • Bin to Fit Frame

    Bin to Fit Frame will calculate a bin factor as a power of 2 that will allow the entire data space to be displayed in the current frame.

    Bin Block Factor

    A value greater or equal to zero. This value indicates the number of pixel values that will fall into a particular bin.

    Bin Buffer Size

    The overall size of the image generated. This has no relation to min and max values of the columns used to create the image. The image generated is of BIN BUFFER SIZE, centered at the current view center.

    Binning Parameters

    Allows the user to specify an arbitrary binning parameters, including filters.
