GaiaCMD
A Python package for plotting Gaia Color-Magnitude Diagrams for TESS white dwarf pulsation catalogs.
Give it a CSV of TIC IDs — it queries Gaia EDR3 and produces a CMD with all your targets plotted.
Install
pip install gaiacmd
Usage
Python
from gaiacmd import run_cmd, plot_cmd
state = run_cmd("my_tics.csv")
plot_cmd(state)
Command line
gaiacmd --csv my_tics.csv
Input format
A CSV file with a TIC column:
TIC
141872267
123456789
987654321
Output
- A Gaia CMD figure with your WD targets plotted as red dots
- A grey background cloud of field stars (1° radius per target)
- The DAV (ZZ Ceti) instability strip overlay
- Saved as
gaia_cmd_wds.png
Resume support
Progress is saved to a checkpoint file after every TIC. If the run is interrupted, just re-run the same command — it will pick up where it left off. Delete gaia_cmd_checkpoint.pkl to start fresh.
