Pipeline to recover astrometry and photometry of Solar System Objects in imaging surveys

Max Mahlke | arXiv | Thesis | CV | Contact

I'm an astronomer studying the minor bodies of the Solar System. My repositories include several open-source tools for the minor-body community and for researchers in general.

I'm available for PostDoc starting December 2024. Please do not hesitate to get in touch should you or someone you know offer a position that may apply to my research profile.

Minor Bodies

• rocks - A python and command-line interface to all kinds of asteroid data except for reflectance spectra.
• classy - A python and command-line interface to asteroid reflectance spectra. And it classifies them, too.
• ssos - Pipeline for automatic detection and recovery of minor bodies in astronomical images.
• mpc - Make local queries to the observations database of the Minor Planet Center.
• Les Houches Index of Small-Body Tools - Maintained index of tools for Asteroids, Comets, and Meteorites
• Timeline of the asteroid taxonomy

General

• fuzzy-ads - A command-line interface to NASA ADS
• mcfa - A python implementation of Mixture of Common Factor Analyzers dimensionality reduction / clustering
• re-research - A TeX publication template focused on reproducible research
• Solar-System Orbiter - Simulation of Solar System including Hohmann transfers between planets

ssos's Issues

Error after SWARP execution

Hi,

While using the default settings of the pipeline I have found a problem that wasn't happening before. I'm having this issue since the last time I updated ubuntu.

In a virtual machine from other pc I have installed ubuntu from scratch with only what's needed to run this pipeline, but I get exactly the same error.

I can "bypass" this problem if I add the following text to hdulist.py, from the astropy package, in the line 967.

self._file.close()

This file is located in ... /lib/python3.7/site-packages/astropy/io/fits/hdu. I know that I shouldn't touch this files but, for now with that change, the pipeline actually finishes without errors.

Here I attach a copy of the main error.
