def superimpose_bound_cen(self, center, size, label,
color='red', coord_in='C'):
'''Superimpose the footprint of a survey on the background image
by giving input radec boundaries for the map. Boundaries are defined
as the center and "radius" in ra/dec.
Parameters
----------
center : array-like with shape (2,)
The center of the survey (degrees). ra/dec, gall/galb, etc.
size : array-like with shape (2,)
The length of the edge of the rectangle in degrees
label : string
The label to put on the colorbar for this survey
color : string or array-like with shape (3,)
The color to use when overlaying the survey footprint. Either a
string or rgb triplet. Default : 'red'
coord_in : 'C', 'G', or 'E'
The coordinate system of the input parameters. 'C' would mean
input values are in ra,dec. Default : 'C'

def get_rectangle(self, survey_name):
'''Generates a healpix map for a given survey given a center point
and edge length of the rectanlge.
Handler in .cfg file: "rectangle"
Parameters
----------
survey_name : string
Configuration file block specifying survey parameters
Returns
-------
hpx_map : array-like
The healpix map associated with the survey
Notes
-----
The configuration file must contain a 'center', a 'size', and a
'coord' entry. The 'size' entry must contain the lon,lat length of the
edge of the rectangle. The nside of the output map is the same as the
nside specified in the initialization of this class.
