### Sentinelleof CLI Help

Source: https://github.com/scottstanie/sentineleof/blob/master/README.md

Displays all available options and usage instructions for the Sentinelleof command-line tool. Use this to understand the full range of parameters for downloading orbit files.

```bash
$ eof --help
Usage: eof [OPTIONS]

  Download Sentinel precise orbit files.

  Saves files to `save-dir` (default = current directory)

  Download EOFs for specific date, or searches for Sentinel files in --path.
  Will find both ".SAFE" and ".zip" files matching Sentinel-1 naming
  convention. With no arguments, searches current directory for Sentinel 1
  products

Options:
  -p, --search-path DIRECTORY     Path of interest for finding Sentinel
                                  products.   [default: .]
  --save-dir DIRECTORY            Directory to save output .EOF files into
                                  [default: .]
  --sentinel-file PATH            Specify path to download only 1 .EOF for a
                                  Sentinel-1 file/folder
  -d, --date TEXT                 Alternative to specifying Sentinel products:
                                  choose date to download for.
  -m, --mission [S1A|S1B|S1C]     If using `--date`, optionally specify
                                  Sentinel satellite to download (default:
                                  gets S1A, S1B, and S1C)
  --orbit-type [precise|restituted]
                                  Optionally specify the type of orbit file to
                                  get (default: precise (POEORB), but fallback
                                  to restituted (RESORB))
  --force-asf                     Force the downloader to search ASF instead
                                  of ESA.
  --debug                         Set logging level to DEBUG
  --cdse-access-token TEXT        Copernicus Data Space Ecosystem access-
                                  token. The access token can be generated
                                  beforehand. See https://documentation.datasp
                                  ace.copernicus.eu/APIs/Token.html
  --cdse-user TEXT                Copernicus Data Space Ecosystem username. If
                                  not provided the program asks for it
  --cdse-password TEXT            Copernicus Data Space Ecosystem password. If
                                  not provided the program asks for it
  --cdse-2fa-token TEXT           Copernicus Data Space Ecosystem Two-Factor
                                  Token. Optional, unless 2FA Authentification
                                  has been enabled in user profile.
  --ask-password                  ask for passwords interactively if needed

  --netrc-file TEXT               Path to .netrc file. Default: ~/.netrc
  --max-workers INTEGER           Number of parallel downloads to run. Note
                                  that CDSE has a limit of 4
  --help                          Show this message and exit.

### Run sentineleof with custom paths

Source: https://github.com/scottstanie/sentineleof/blob/master/README.md

Use the `eof` command with `--search-path` to specify a directory containing Sentinel-1 scenes and `--save-dir` to define where the orbit files should be saved. The save directory will be created if it doesn't exist.

```bash
eof --search-path /path/to/safe_files/ --save-dir ./orbits/
```

--------------------------------

### Download EOFs using Python API

Source: https://github.com/scottstanie/sentineleof/blob/master/README.md

Demonstrates how to use the `download_eofs` function from the `eof.download` module. Supports passing dates as datetime objects or strings, and optionally specifying the Sentinel mission.

```python
from eof.download import download_eofs

download_eofs([datetime.datetime(2018, 5, 3, 0, 0, 0)])
```

```python
download_eofs(['20180503', '20180507'], ['S1A', 'S1B', 'S1C'])
```

--------------------------------

### Run sentineleof to download orbit files

Source: https://github.com/scottstanie/sentineleof/blob/master/README.md

Execute the `eof` command to download precise or restituted orbit files. If POEORB files are not available, it will automatically download RESORB files. Ensure your `~/.netrc` is configured for CDSE authentication.

```bash
eof
```

--------------------------------

### Configure .netrc for CDSE Authentication

Source: https://github.com/scottstanie/sentineleof/blob/master/README.md

Store your Copernicus Data Space Ecosystem username and password in a `~/.netrc` file for authentication. This is required for using CDSE-provided orbits.

```shell
machine dataspace.copernicus.eu
  login MYUSERNAME
  password MYPASSWORD
```
