===============================================================

.. data:: hawki_step_detect_obj

Synopsis
--------

(OBSOLETE) Object detection recipe

Description
-----------

(OBSOLETE) hawki_step_detect_obj -- hawki detect objects recipe.

This recipe detects objects from the combined image creating a mask
and a list of object properties
The input of the recipe files listed in the Set Of Frames (sof-file)
must be tagged as:
combined.fits COMBINED
The recipe creates as an output:
hawki_step_detect_obj_mask.fits (OBJ_MASK): A mask with 1 where the objects are present and 0 elsewhere
hawki_step_detect_obj_stars.fits (OBJ_PARAM): A table with the detected objects characteristics
Return code:
esorex exits with an error code of 0 if the recipe completes successfully
or 1 otherwise

Constructor
-----------

.. method:: cpl.Recipe("hawki_step_detect_obj")
   :noindex:

   Create an object for the recipe hawki_step_detect_obj.

::

   import cpl
   hawki_step_detect_obj = cpl.Recipe("hawki_step_detect_obj")

Parameters
----------

.. py:attribute:: hawki_step_detect_obj.param.median_smooth

    box size for a median smoothing of the image before the detection  (int; default: 3) [default=3].
.. py:attribute:: hawki_step_detect_obj.param.detect_sigma

    detection level (float; default: 7.0) [default=7.0].
.. py:attribute:: hawki_step_detect_obj.param.growing_radius

    radius of convolution kernel to apply to objects (int; default: 5) [default=5].


The following code snippet shows the default settings for the available 
parameters.

::

   import cpl
   hawki_step_detect_obj = cpl.Recipe("hawki_step_detect_obj")

   hawki_step_detect_obj.param.median_smooth = 3
   hawki_step_detect_obj.param.detect_sigma = 7.0
   hawki_step_detect_obj.param.growing_radius = 5


You may also set or overwrite some or all parameters by the recipe 
parameter `param`, as shown in the following example:

::

   import cpl
   hawki_step_detect_obj = cpl.Recipe("hawki_step_detect_obj")
   [...]
   res = hawki_step_detect_obj( ..., param = {"median_smooth":3, "detect_sigma":7.0})
