Open QDP File

A QDP file usually refers to an ASCII text file produced by QDP, which is used in X-ray astronomy. It also represents the data file format used by QlikView, a leading data visualization and business intelligence (BI) tool. Two major ways to use these files are through data mapping in the field of X-ray astronomy (through QDP- or XSPEC-formatted files) and through data analysis using Business Intelligence tools (using QlikView). We'll discuss each one separately.

Using QDP files in X-ray astronomy

The QDP (Quick and Dandy Plotter) software is popular among X-ray astronomers for drawing ASCII graphs. Naturally, the .qdp files are ASCII text files that help astronomers plot data. To view or edit such files, one needs a text editor. You can use a basic text editor like Notepad, Sublime text, or you can opt for science-specific text editors like Atom (https://atom.io/). The website of High Energy Astrophysics Science Archive Research Center (HEASARC) provides comprehensive guidelines on drawing and plotting graphs with the QDP files.

Using QDP files with QlikView

QDP files also refer to proprietary data files produced by QlikView. QlikView is a top-ranked BI tool used to convert raw data into knowledge. QlikView handles QDP files, containing all relevant QlikView data in one compressed file. To open such a file, you'll need the QlikView software, which is available on their official website ( QlikView ). You can then use QlikView to analyze the data contained in the QDP file.

QDP File Important Information

QDP files, either used in X-ray astronomy plotting or in data analysis with QlikView, can assist in performing various tasks related to data visualization and conversion. It's crucial to recognize the origin of the QDP file you're dealing with. Understanding the correct context will ensure that you can use the right software and techniques to effectively open and interpret the data within the file. Ensure you keep your QDP files from being corrupted by regularly backing them up and keeping your software updated. These practices will also safeguard your data and ensure smooth operation.
