Introduction

In this tutorial we learn how to install ast on Fedora 34.

What is `ast`

The AST library provides a comprehensive range of facilities for attaching world coordinate systems to astronomical data, for retrieving and interpreting that information and for generating graphical output based on it. It’s main selling points are * Ease of use. * Facilities for generating plots of generalized non-linear, potentially discontinuous 2-D or 3-D coordinate systems, with detailed control of the appearance of the plot. * Facilities for converting transparently between different coordinate systems, including a wide range of celestial, spectral and time coordinate systems. * Facilities for searching a general collection of connected coordinate systems for a coordinate system with any given set of characteristics. * Allows code for handling WCS information to be written in a general way without regard to the specific nature of the coordinate systems being handled (i.e. whether they represent sky positions, spectral positions, focal plane positions, pixel positions, etc). * Flexible system for saving and retrieving WCS information, including (but not limited to) a range of different popular FITS descriptions. * Written in C but has interfaces for C, Fortran, Java (via JNI), Perl, and UNIX shell. * Extensive documentation. ast 9.2.3 2.fc34 x86_64 1.8 M ast-9.2.3-2.fc34.src.rpm fedora A Library for Handling World Coordinate Systems in Astronomy http LGPLv3+ and LGPLv2+ The AST library provides a comprehensive range of facilities for attaching world coordinate systems to astronomical data, for retrieving and interpreting that information and for generating graphical output based on it.

We can use yum or dnf to install ast on Fedora 34. In this tutorial we discuss both methods but you only need to choose one of method to install ast.

Install ast on Fedora 34 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00
Fedora 34 openh264 (From Cisco) - x86_64        1.4 kB/s | 989  B     00:00
Fedora Modular 34 - x86_64                       68 kB/s | 6.5 kB     00:00
Fedora 34 - x86_64 - Updates                    3.5 kB/s | 6.2 kB     00:01
Fedora Modular 34 - x86_64 - Updates             17 kB/s | 5.9 kB     00:00
Metadata cache created.

After updating yum database, We can install ast using dnf by running the following command:

sudo dnf -y install ast

Install ast on Fedora 34 Using yum

Update yum database with yum using the following command.

sudo yum makecache --refresh

The output should look something like this:

Fedora 34 - x86_64                               20 kB/s | 6.6 kB     00:00
Fedora 34 openh264 (From Cisco) - x86_64        1.4 kB/s | 989  B     00:00
Fedora Modular 34 - x86_64                       68 kB/s | 6.5 kB     00:00
Fedora 34 - x86_64 - Updates                    3.5 kB/s | 6.2 kB     00:01
Fedora Modular 34 - x86_64 - Updates             17 kB/s | 5.9 kB     00:00
Metadata cache created.

After updating yum database, We can install ast using yum by running the following command:

sudo yum -y install ast

How To Uninstall ast on Fedora 34

To uninstall only the ast package we can use the following command:

sudo dnf remove ast
