TipTop v1.5.1, P3 v1.6.2 and MASTSEL v1.5.2 are now available! 🎉

This release focuses on improving the software architecture and interoperability of the TipTop ecosystem while reducing latency for service-oriented deployments. These developments provide the software foundations required to support the growing range of scientific and operational applications built around TipTop, including exposure-time calculation, observation preparation, and future PSF reconstruction services.

TipTop v1.5.0, P3 v1.6.0 and MASTSEL v1.5.0 are now available! 🎉

This release focuses on improving the numerical robustness and spatial consistency of TipTop's analytical engine. These developments are particularly important for operational applications, where PSFs must remain reliable over a broad range of observing conditions, detector samplings, and wavelength ranges.

Highlights include improved multi-wavelength PSF generation, robust handling of odd and even Fourier grids, physically consistent atmospheric refraction modelling, and enhanced spatial resampling of PSFs.

TipTop v1.4.0, P3 v1.5.1 and MASTSEL v1.4.3 are here! 🎉

This release introduces precision management, allowing users to trade a small amount of numerical accuracy for faster computations and lower memory usage.

✨ What’s new

  • Added precision control in the COMPUTATION section.

  • Default precision remains double precision (float64, omplex128) to ensure the same accuracy as previous versions.

  • Optional single precision mode can now be enabled (see the parameters page)

🚀 Benefits of single precision:

  • 10–20% faster computations
  • ~30% lower memory usage

Small differences in results may appear (typically 1–2% in SR), but this option is particularly useful for large simulations or memory-limited environments.

🛠️ Additional updates

  • Fixed several bugs identified during recent testing.

Update now and enjoy the latest improvements!

TipTop v1.3.33, P3 v1.4.13 are here! 🎉

This release improves memory usage in P3, especially in the aliasing PSD computation that previously dominated memory in large simulations.

✨ What’s new

  • Improved memory management in the p3.ao.fourierModel module: more intermediate variables are now released via the reduce_memory option (enabled by default in TipTop).

  • Reworked aliasing PSD computation with more memory-efficient array handling.

👉 Heavy TipTop/P3 cases that previously required large amounts of RAM should now run more easily and reliably.

Update now and enjoy the latest enhancements 🚀

On January 26, 2026, the TipTop team was delighted to take part in a dedicated TipTop Meeting held at ESO Headquarters in Garching.

This meeting was a great opportunity to bring together developers and ESO stakeholders to discuss the current status of TipTop, its ongoing integration into ESO tools for observation preparation, and the exciting perspectives for future use, including upcoming instruments and the ELT. We also had fruitful discussions on possible improvements and new use cases for the tool.
