ValueError: Semi-minor axis must be in ]0, a[

[Kincaidr]

Hi,

I am trying to create a MOC as shown in your example here docs/astropy/examples.ipynb.

If i follow these steps exactly:

region_center = SkyCoord(ra=35.30109, dec=-4.45962, unit='deg')
search_radius = 1*u.deg

from mocpy import MOC

moc_xxl = MOC.from_elliptical_cone(
    lon=region_center.ra,
    lat=region_center.dec,
    a=search_radius,
    b=search_radius,
    pa=0*u.deg,
    max_depth=14
)

I get:

ValueError: Semi-minor axis must be in ]0, a[

If i make a slight modification of a < b :

a_deg=1*u.deg
b_deg = 0.999*u.deg

moc_xxl = MOC.from_elliptical_cone(
    lon=region_center.ra,
    lat=region_center.dec,
    a=a_deg,
    b=b_deg,
    pa=0*u.deg,
    max_depth=14
)
Then it works
