Description
I am in the 'getting_started' section of the DESI Jupyter notebook. Cell 14 has the code:
Tile file from SURVEY='sv3' and PROGRAM='dark'
tile_file = f'{specprod_dir}zcatalog/ztile-sv3-dark-cumulative.fits'
t_tile = Table.read(tile_file, hdu=1)
ra_tile = t_tile['TARGET_RA']
dec_tile = t_tile['TARGET_DEC']
We will use Tile #30 for the example below
selec_tile = t_tile['TILEID']==30
When I try to execute that code I receive the following error:
FileNotFoundError Traceback (most recent call last)
Cell In[14], line 4
