Load in the data

Harry: the exact routine may not work, I had to edit the raw .txt file a little

In [124]:
cosmo = FlatLambdaCDM(H0=100, Om0=0.307)

data0 = pd.read_csv("/mnt/users/rstiskalek/csiborgtools/data/top10_pwave_coords.txt", sep='\s+')
data = {}

data["id"] = np.array([int(x.split("_")[-1]) for x in data0["halo_ID"].values])
data["l"] = data0["l[deg]"].values
data["b"] = data0["b[deg]"].values
data["dist"] = cosmo.comoving_distance(data0["z"].values).value

print(data["dist"])
