Yak-Shaving für Astronomen

Als Yak-Shaving bezeichnet man iterative Prozesse, bei denen man, um ein Problem zu lösen, immer erst ein anderes Problem vorher lösen muss, das wiederum die Lösung von noch einem anderen Problem erfordert, und so weiter. Mein Ausgangsproblem: Ich habe ein Bild aus einem Teleskop und will einen Katalog der Sterne in diesem Bild machen. Dafür gibt es eine Reihe von vorgefertigten Programmen, ich muss das nicht selbst programmieren. Eines der gebräuchlichsten heißt “SExtractor”, kurz für “Source Extractor”, und, ja, der Scherz war vermutlich mal für drei Minuten lustig, damals, als SExtractor das Licht der Welt erblickte, also circa im Jahr 2000. Ich habe genau dieses Programm schon damals verwendet, es war mit Abstand am einfachsten und schnellsten für diese Aufgabe. 

Aber damals hatte ich auch noch einen Linux-Computer, der von einem IT-Experten gewartet wurde. Die Software-Installation beschränkte sich für mich darauf, eine Email an diesen Experten zu schicken. So war es auch 2005, als ich meinen ersten richtigen Job antrat, und auch 2007, beim zweiten: Ich bestellte beim Arbeitgeber einen neuen Rechner, und sagte gleich dazu, welche Software ich benötige, fertig. Diese Zeiten sind vorbei, heute sind wir alle System-Administratoren und Software-Yak-Shaver. Astronomie machen wir auch noch.

Mittlerweile ist SExtractor in der Version 2.19.5, und existiert nur als Quellcode, wie so oft bei Spezialsoftware für Astronomen. Man kann es aber einfach auf jedem Rechner kompilieren, der Linux-kompatibel ist, also theoretisch auch auf Macs, solange alle nötigen Libraries schon da sind. Sind sie natürlich bei mir nicht. Diese “Dependencies”, also Software, die andere Software voraussetzt, die wieder andere Software voraussetzt, die Versoftwarung von Yak-Shaving, sind ein generelles Problem unseres Software-Ökosystems, und jeden Tag huldige ich Programmen, die einfach so laufen. Topcat! DS9! Seid umarmt. Zum Glück gibt es zum Management dieser Dependencies wieder andere Software. Ich erfahre von Macports, das nach der Installation auch beinahe sofort läuft, und Macports weiß schon, wie man SExtractor installiert. Eine Weile geht alles gut.

Dann teilt mir Macports mit, das es noch eine vollständige Installation von XCode benötigt. XCode gibt es beim Apple Store, und es dauert auch nur eine Viertelstunde, bis ich dort Zugriff habe – der Account zeigt auf eine uralte Emailaddresse, und die Sicherheitsfragen sind verwirrend. Mein erster Lehrer? Wer sollte das gewesen sein? Dann finde ich heraus, dass die angebotene Version von XCode nur auf einem Betriebssystem läuft, das ein paar Versionen jünger ist als meines. Jetzt gibt es zwei Möglichkeiten: Entweder das Betriebssystem auf den neuesten Stand bringen, was zur Folge haben wird, das diverse andere Software auch neu installiert werden muss, und eventuell nicht mehr geht. Oder einen Developer-Account kaufen, und damit Zugriff auf alte XCode-Versionen zu haben. Beides rote Linien in meiner Yak-Shaving-Philosophie.

Oder aber das ursprüngliche Problem mit einer ganz anderen Software lösen. Oder es überhaupt nicht lösen, ein viel zu selten benutzter Problembewältigungsansatz.

i want you guys to know that there's an image processing software used in astronomy called SExtractor (Source Extractor), and people are always talking about sextractor this, sextractor that

Research Day 32, Blog 30

Title: Article Review: An Improved Method for Object Detection in Astronomical Images

Introduction: This post provides a brief review of the article titled "An improved method for object detection in astronomical images," which was the focus of our learning on Tuesday, June 27. The article presents an enhanced approach for detecting galaxies and stars in astronomical images, highlighting improvements in accuracy and the detection of faint objects.

Summary of the Article: The article introduces an advanced method for detecting objects of interest in astronomical images. The approach involves a global detection scheme followed by a refined detection procedure using watershed segmentation to divide the image into irregular sub-regions. Adaptive noise reduction and a layered strategy are applied to detect bright and faint objects. Additionally, a multi-threshold technique is employed to separate blended objects. The method demonstrates superior performance compared to SEXTRACTOR, achieving higher true detection rates (91% versus 83%) and improved detection of very faint objects, up to 2 magnitudes fainter than SEXTRACTOR.

Relevance to Individual Research: While the previous day was dedicated to reading about source detection approaches, this article is an updated version of the previous one. It helped us gain a broader understanding of our research project "Counting Objects in Astronomical Photographs". The insights from this article can provide valuable guidance for enhancing the accuracy and effectiveness of my image segmentation algorithm.

Conclusion: The article "An improved method for object detection in astronomical images" introduces a refined approach that enhances the detection of galaxies and stars in astronomical images. The combination of global detection, watershed segmentation, adaptive noise reduction, layered strategy, and multi-threshold technique improves object detection accuracy. The relevance of this article to our ongoing image segmentation project highlights the importance of incorporating advanced techniques to enhance the efficiency and precision of our research endeavors.

just read SExtractor in an observational astronomy paper; i swear to god someone is taking piss out there

[icelandofficial]

All of the complications with the telescipe software have veen giving me so much anxiety about the thing that im supposed to enjoy doing (observing), and its been taking so long to get data for so many reasons, senior project is really just :/ worried about getting it all done on time

[hansfallada]

i just hate that they called the Source Extractor software i'm working with SExtractor. like why would you put the word sex in there :/
