Data Visualization

One of the greatest benefits from having a web user interface (UI) is the great flexibility it provides without having to install any special software and the data is downloaded through channels we use in our everyday life.

Understanding the UI

We will go into details later but for now this is what you see most of the time. It is meant to be simple to understand but we will go into explaining every part.

Data detailed view.

Table view, better for filtering data.

For a detailed exploration we will divide the view in several subsections, for their global position please consider the following image.

User Controls

File Index

This area allows you to navigate the files, they are ordered from newest to oldest, if you want to filter the data you should go to table mode by clicking View as Table.

In this area you can also see only combined calibration files such as, master BIAS and master FLAT, those are visible to everyone.

Visualization Area

Example of a static data visualization.

In this area you see the plots or the images. There is an interactive way that uses Bokeh but is slower. and for now it only allows you to zoom in or out.
