I have been trying to load the GaiaTGE map, but I am unable to create the query instance class because the index error.
Currently, I have been trying to load the map using the following code in a Jupyter notebook.
import dustmaps
import dustmaps.gaia_tge
from dustmaps.config import config
# Config...
config.reset()
config["data_dir"] = "/home/sparrow/baystar/"
# Downloading the map if needed...
dustmaps.gaia_tge.fetch()
# Load the map.
gaia_map = GaiaTGEQuery()
But, the last line fails with...
---------------------------------------------------------------------------
IndexError Traceback (most recent call last)
Cell In[6], line 1

File ~/.local/lib/python3.14/site-packages/dustmaps/gaia_tge.py:117, in GaiaTGEQuery.__init__(self, map_fname, healpix_level)

116 for offset in range(mult_factor):

118 else:
119 raise ValueError(
120 '`healpix_level` must be either an integer or "optimum"'
121 )
IndexError: index 19200 is out of bounds for axis 0 with size 0
What would be the best solution to download and utilize the Gaia maps?
