FLI module for pyobs

This is a pyobs module for FLI cameras and filter wheels.

FLI kernel module

The FLI kernel module needs to be installed on the system.

Install pyobs-fli

Clone the repository:

git clone https://github.com/pyobs/pyobs-fli.git
cd pyobs-fli

Install it with uv:

uv sync

Alternatively, with plain venv/pip:

python3 -m venv .venv
source .venv/bin/activate
pip install .

Configuration

The FliCamera class is derived from BaseCamera (see pyobs documentation) and adds a single new parameter:

setpoint:
    The initial setpoint in degrees Celsius for the cooling of the camera.

The class works fine with its default parameters, so a basic module configuration would look like this:

class: pyobs_fli.FliCamera
name: FLI camera
setpoint: -20.0

For cameras with an FLI filter wheel, use FliFilterWheel, which takes a list of filter names:

class: pyobs_fli.FliFilterWheel
name: FLI filter wheel
filter_names: [Red, Green, Blue, Clear, Halpha]

Dependencies

• pyobs-core for the core functionality.
• Cython for wrapping the FLI SDK.
• Astropy for FITS file handling.
• NumPy for array handling.
