CFHT-MegaCam Filters
--------------------

CFHT-MegaCam filters taken from `here
<http://svo2.cab.inta-csic.es/theory/fps/index.php?mode=browse&gname=CFHT&gname2=MegaCam&asttype=>`__. The
response is the total transmission, including the full telescope transmission
(mirror+optics+CCD) plus 1.25 airmasses of atmospheric attenuation. Note that
*u*\ :sup:`*` refers to the old (first-generation, through 2015) bandpass,
whereas the *u*-band curve is the newer (post-2015, third-generation) filter
curve.

The command below produces the figure::

megacam = speclite.filters.load_filters('cfht_megacam-*')
speclite.filters.plot_filters(megacam, legend_ncols=2, response_limits=[0, 0.7])
