To make this website I have used the following programs:

-JS9: software that I have used to analyze and obtain the graphics and elements of the different objects in the sky.

-Image J: program that calculate the areas of the peaks.

-Mapper.js: The map files (source maps) are responsible for descompiling the Javascript code so that you can debug it in the browser

-Image map: generator that I have used to place the different objects in the sky in an image map of the constellation of Canis Majoris.

-Rextester: program to obtain a graph of the Cepheid.

-Excel: Spreadsheet that I have used to put data on the Cepheids and where I have obtained a graph and a formula

-R: is used for statistical data processing and analysis

-Google Schoolar: search engine that I have used to find documents and articles of other scientists to be able to compare my results with those of other scientists.

-Neocities: web hosting service that I have used to upload my website.

-Chandra:  is a NAS telescope that observes black holes, quasars, supernovae and similar objects, all of them hight-energy sources of the universe. Chandra can see a part of the cosmos that is invisible to the human eye.

-Wikipedia: free encyclopedia where I have found information about this project.

-The sky live: website where I found the image of the constellation of Canis Majoris.

-ezyzip: zip file format that I have used to compress files.

-Laboratory of exoplanets: laboratory where I have made a photo with an arizona telescope to an object in the sky.

-In-The-Sky.org: website that I have used to find information about some of the sky objects (declination, right ascension, ...).

-Hydrogen energies and spectrum: I have used this website to search for the energies of the different elements.

-Open exoplanet catalogue: website that I have used to find information about some of the sky objects (declination, right ascension, ...).

-Intranet de Harvard: website that I have used to find each of the objects in the sky and much more information to do my project.
