Quick plotters

The madcubapy.visualization package also offers various functions to quickly perform some tasks that do not need to be saved. The functions described in this page work on MadcubaMap and CCDData objects.

Quickly plot a map

To quickly show the contents of a MadcubaMap or CCDData object in a pop-up window, we can use the quick_show() function on the object.

>>> quick_show(madcuba_map)

This function accepts additional parameters that are passed to matplotlib.pyplot.imshow().

>>> quick_show(madcuba_map, cmap='jet', norm='log')

Compare two maps

We can compare if two map objects are equal with the are_equal() function. This function returns a boolean value indicating if they are equal or not.

This function can also plot the maps, and show the residuals of their substraction if show_maps is set to True:

>>> are_equal(madcuba_map, madcuba_map.ccddata, show_maps=True)
Checking if the two maps are equal
True

Here we see that the CCDData inside the ccddata attribute of a MadcubaMap contains the same information.
