How To Install python3-pymoc on Kali Linux
Introduction
In this tutorial we learn how to install python3-pymoc on Kali Linux.
What is python3-pymoc
python3-pymoc is:
PyMOC provides a Python compatible library for handling MOCs.
Frequently astronomical survey catalogues or images are sparse and cover only a small part of the sky. In a Multi-Order Coverage map the extent of data in a particular dataset is cached as a pre-calculated mask image. The hierarchical nature enables fast boolean operations in image space, without needing to perform complex geometrical calculations. Services such as VizieR generally offer the MOC masks, allowing a faster experience in graphical applications such as Aladin, or for researchers quickly needing to locate which datasets may contain overlapping coverage.
The MOC mask image itself is tessellated and stored in NASA HealPix format, encoded inside a FITS image container. Using the HealPix (Hierarchical Equal Area isoLatitude Pixelization) tessellation method ensures that more precision (pixels) in the mask are available when describing complex shapes such as approximating survey or polygon edges, while only needing to store a single big cell/pixel when an coverage is either completely inside, or outside of the mask. Catalogues can be rendered on the mask as circles.
There are three methods to install python3-pymoc on Kali Linux. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
Install python3-pymoc Using apt-get
Update apt database with apt-get using the following command.
sudo apt-get updateAfter updating apt database, We can install python3-pymoc using apt-get by running the following command:
sudo apt-get -y install python3-pymocInstall python3-pymoc Using apt
Update apt database with apt using the following command.
sudo apt updateAfter updating apt database, We can install python3-pymoc using apt by running the following command:
sudo apt -y install python3-pymocInstall python3-pymoc Using aptitude
If you want to follow this method, you might need to install aptitude on Kali Linux first since aptitude is usually not installed by default on Kali Linux. Update apt database with aptitude using the following command.
sudo aptitude updateAfter updating apt database, We can install python3-pymoc using aptitude by running the following command:
sudo aptitude -y install python3-pymocHow To Uninstall python3-pymoc on Kali Linux
To uninstall only the python3-pymoc package we can use the following command:
