- Telescope: {missions[mission]["fullname"]} ({mission.upper()})
- Split: `{split}`
- Frequency Band (GHz): `{band}`
See [data access](./dc0.html#data-access) on the DC0 page.
Access the data through the Globus web interface: [](https://app.globus.org/file-manager?origin_id={ENDPOINT}&origin_path=%2Fdatareleases%2Fdc0%2Fmission%2F{mission}%2Fsplit{split}%2F{band}%2F)
Download the [file manifest](https://{DOMAIN}.data.globus.org/datareleases/dc0/mission/{mission}/split{split}/{band}/manifest.json) for the exact file sizes and checksums.
