    • block factor

    Set the current blocking factor. It does not have to be an integer.
    Syntax:  block factor numeric
                  block factor to numeric
                  block factor to numeric about coordinate # in physical coordinates
    Example: block factor 4
             block factor to 2
             block factor to 2 about 100 100

    block function

    Set the current blocking mode.
    Syntax:  block function [average | sum]
    Example: block function sum

    block buffer size

    Set the current blocking buffer size.
    Syntax:  block buffer size integer
    Example: block buffer size 1024

    block to fit

    Set the current blocking factor such that the entire image will fit the current frame size. The blocking factor will be rounded up to the next power of 2.
    Syntax:  block to fit
    Example: block to fit

    get block factor

    Return the current blocking factor.
    Syntax:  get block factor precision
    Example: get block factor default

    get block function

    Return the current blocking function. A value of AVERAGE or SUM is returned.
    Syntax:  get block function
    Example: get block function

    get block buffer size

    Return the current blocking buffer size.
    Syntax:  get block buffer size
    Example: get block buffer size

    get block cursor

    Return the coordinate in physical coordinates that is the center of the blocking operation.
    Syntax:  get block cursor
    Example: get block cursor

    has block

    Return true if FITS is a binary table
    Syntax:  has block
    Example: has block
