This is my code:

from matplotlib import pyplot as plt

dec = pd.read_csv('POLAR.txt', sep="    ", header=None, skiprows=1)

ra = [0,30,60,90,120,150,180,210,240,270,300,330] 
ra = [x/180.0*np.pi for x in ra]

ax = plt.subplot(111, projection='polar')
plt.polar(ra, dec, 'ok')
plt.plot(ra,dec, data=ra , marker='o', color='olive', linewidth=2)
ax.set_yticklabels([])

I'm still not sure how to connect the last and first points though. This is what I get:

enter image description here

I'm wondering how can I connect the points with curved lines? And is there anyway to get the equation of this peanut shaped plot?
