cabaret

cabaret is a Python package to simulate astronomical images using the GAIA catalog of stars.

Installation

You can install cabaret in a Python (>=3.11) environment with

pip install cabaret

or from a local clone

git clone https://github.com/ppp-one/cabaret
pip install -e cabaret

You can test the package has been properly installed with

python -c "import cabaret"

Example

Basic image

To generate an image from RA/DEC coordinates and a field of vue specified in degrees:

import cabaret

ra, dec = 12.3323, 30.4343 # in degrees
exposure_time = 10 # in seconds

image = cabaret.generate_image(ra, dec, exposure_time)

and to display the image (matplotlib required here):

import matplotlib.pyplot as plt

plt.imshow(image)

Using the camera characteristics

To adjust the physical characteristics of the camera, you can define and pass a Camera object. Similary, one can pass Telescope and Site objects to define the telescope and site characteristics, respectively.

import cabaret
from cabaret import Camera

camera = Camera(read_noise=10, gain=1)

ra, dec = 12.3323, 30.4343 # in degrees
exposure_time = 10 # in seconds

image = cabaret.generate_image(ra, dec, exposure_time, camera=camera)
