-## Mahon Fitting
+## Linear regression with `CEREsFit`
 
-In order to fit a linear regression to measurements with uncertainties in both axes, the routine by <a href="https://www.tandfonline.com/doi/abs/10.1080/00206819709465336" target="_blank">Mahon (1996)</a>, also known as the “New York” regression, should be used. Along with the <a href="https://doi.org/10.3847/2041-8213/aabba9" target="_blank">Trappitsch et al. (2018)</a> publication we published a tool to easily apply the Mahon fitting routine to any dataset. The tool, including a detailed README file, can be found on <a href="https://github.com/LLNL/MahonFitting" target="_blank">the respective GitHub site</a>.
+In [Stephan and Trappitsch (2023)](/publication/stephan-23-unc) we presented the methods to calculate linear regressions for measurements that have uncertainties in both dimensions. For this work, we also implemented a python tool `CEREsFit`, which is freely available on <a href="https://pypi.org/search/?q=ceresfit" target="_blank">`pypi`</a> and <a href="https://github.com/galactic-forensics/CEREsFit" target="_blank">GitHub</a>. In the repository, example Jupyter notebooks on how to use the module and how to plot the regressions lines with rotated error bars for correlated uncertainties are also shown.

+We develop our own hardware, mainly for [RIMS](/project/RIMS) applications. However, some of these might be useful for other laser- and mass spectrometry laboratories! Have a look. All of our hardware is released open-source with well documented building instructions, firmware, and python interfaces.
+
+## Digital Outputs: `DigOutBox`
+
+We developped a digital output box (called `DigOutBox`). Our intended use was to control laser shutters with a remote control (while working on the laser), but also from the computer. The box simply applies low (0 V) or high (5 V) voltage to the outputs, which can be fed into the TTL input channel of a laser shutter or any other device.
+
+Since the project was developed for lasers, several safety features are built into the hardware:
+
+- **Software lockout**: The remote control can be configured such that the user can easily lock-out any interaction from the computer
+- **Interlock**: Optionally, an interlock line can be connected, which, when triggered, will close all shutters and keep them closed until untriggered.
+
+The first version of the box can be seen here:
+
+![Image of the DigOutBox with remote control](/img/projects/hwdev/gfl002_setup.jpg)
+
+The box also comes with a python module to communicate from your own program, and with a GUI for computer control - assuming the software lockout is not triggered!
+
+If you are interested, have a look at the <a href="https://github.com/galactic-forensics/DigOutBox" target="_blank">GitHub repository</a> and our <a href="https://digoutbox.readthedocs.io/" target="_blank">detailed documentation</a> of the project.

 abstract: "In order to measure tungsten isotopic composition in presolar stardust grains that contain a limited number of atoms, we developed a new three-photon three-color resonance ionization scheme using titanium–sapphire lasers and the Laser Ionization of Neutrals (LION) instrument at Lawrence Livermore National Laboratory. The first two transitions can be easily saturated, while approximately 84% of available atoms can be ionized in the third transition with our current laser irradiance. When ionizing from the ground state, measurements demonstrate a W useful yield of 14.4% ± 1.6%. Experiments that intentionally cover a range of laser power and wavelength to simulate potential variations during analysis show that laser-induced W isotopic fractionation, if it occurs, is within measurement error. Overall, this new W resonance ionization scheme can be employed in future studies of atom limited samples to obtain W isotopic measurements."

+abstract: "The Presolar Grain Database (PGD) contains the vast majority of isotope data (published and unpublished) on presolar grains and was first released as a collection of spreadsheets in 2009. It has been a helpful tool used by many researchers in cosmochemistry and astrophysics. However, over the years, accumulated errors compromised major parts of the PGD. Here, we provide a fresh start, with the PGD for silicon carbide (SiC) grains rebuilt from the ground up. We also provide updated rules for SiC grain type classification to unify previous efforts, taking into account newly discovered grain types. We also define a new grain type D, which includes some grains previously classified as ungrouped. Future work will focus on rebuilding the PGD for other kinds of presolar grains: graphite, oxides, silicates, and rarer phases."

 abstract: "Measuring the isotopic composition of trace Zr in presolar stardust grains allows us to study the environment of slow neutron-capture nucleosynthesis in asymptotic giant branch stars. Here, we present a newly characterized Zr resonance ionization scheme that can be saturated with state-of-the-art titanium-sapphire lasers and yields a useful yield of (5.4 ± 0.4)%. Resonance ionization is achieved in two steps: after first being excited with a photon at 319.215nm, neutral Zr atoms are then ionized with a photon at 388.988nm, where both wavelengths are reported as in vacuum."
