Tiny package containing useful parameters from main galaxy surveys (**with units**).

The goal of this project is to provide a Python library with minimal dependencies that centralises galaxy survey properties with adequate reference. Such information tends to be scattered in many places or is often copy/pasted without all of the relevant information like units or sources.

The current parameters and the corresponding units are specified in the [documentation](https://aboucaud.github.io/galcheat/parameters.html)

Getting started
---------------
Install the latest version of the library
```sh
pip install -U galcheat
```

CLI
---

Print the available surveys and associated filters

```sh
galcheat
```

### Options
- **`-s <survey>`**: print information for a given survey
- **`--refs`**: print the source for each parameter
- **`--rich`**: use pretty printing for the terminal (needs the `rich` library installed)
- **`-h, --help`**: get help

### Examples
```sh
galcheat -s LSST         # LSST info
galcheat --refs          # all surveys info with refs
galcheat --refs -s HSC   # HSC info with refs
galcheat -s LSST --rich  # pretty print rich terminal output for LSST info
```

API
---
```python
import galcheat

# Start with the list of available surveys
galcheat.available_surveys

# Retrieve a Survey instance
LSST = galcheat.get_survey("LSST")

# List the available survey filters
LSST.available_filters

# Pick a Filter instance
u_band = LSST.get_filter("u")

# Both Survey and Filter objects have physical attributes
LSST.mirror_diameter

u_band.full_exposure_time

# These attributes are Astropy Quantity objects
# whose value can be retrieved in any desired unit
u_band.psf_fwhm.to_value('arcmin')
```
