       kmo_arithmetic - Perform basic arithmetic on cubes


       esorex kmo_arithmetic [OPTIONS] FILE.sof


       With this recipe simple arithmetic operations, like addition, subtraction, multiplication,
       divison and raising to a power can be performed.

       Since FITS files formatted as F1I, F2I and F3I can contain data (and eventually noise)  of
       either  just  one  IFU  or  of  all 24 IFUs, kmo_arithmetic behaves diffe- rently in these

       When the number of IFUs is the same for both operands, the first IFU of the first  operand
       is processed with the first IFU of the second operand.

       When  the  second operand has only one IFU while the first operand has more IFUs, then the
       all the IFUs of the first operand are processed individually which the IFU of  the  second

       If an operand contains noise and the other doesn´t, the noise will not be processed.

       Noise  is only propagated if both operand contain noise extensions. If the second operator
       is a scalar noise is also propagated, of course.

       If two cubes are given  as  operands,  they  will  be  combined  according  to  the  given
       operator.If  a  cube is given as first operand and an image as second, then it operates on
       each slice of the cube; similarly if a  spectrum  is  given  as  the  second  operand,  it
       operates on each spectrum of the cube; and a number as the second operand operates on each
       pixel of the cube.

       --operator Any of the following operations to perform: ´+´, ´-´, ´*´ or ´/´ (also ´^´ when
       the 2nd operand is a scalar

       --scalar To be provided if a frame should be processed together with a scalar

       --file_extension  Define a string to append to the product filename ARITHMETIC in order to
       get an unique filename

       Note that it is possible to create a configuration file containing  these  options,  along
       with  suitable default values. Please refer to the details provided by the 'esorex --help'

       An   overview   over   the   existing   ESO  pipelines  can  be  found  on  the  web  page

       Basic documentation about the EsoRex program can be found at the esorex (1) man page.

       It is possible to call the pipelines  from  python  using  the  python-cpl  package.   See for further information.
