These pages are an electronic version of a notebook I started years ago, basically when I embarked on my PhD. Having little memory for formulae and numerical values of constants, I decided to copy them in a notebook that would follow me wherever I worked. This book has grown old and now it's a bit too old to carry around. Therefore I am gradually transferring it to a numerical support. This way I can consult it everywhere there is a computer (and there usually is a computer close to where I work) and you can use it too...

There is a vague order but since formulae were accumulated with time, there is no completeness. Here are the contents:

- IRAS related formulae
- ISO related formulae
- Optical magnitudes definitions
- The Sun as a star
- Tables of lines, both atomic and molecular
- Physical constants, i.e. speed of light, h...
- Astronomical constants, i.e. solar mass...

I try to include most of the information inside these pages but some already exists and should not be duplicated so I include here a table of links providing related informations

Arp catalog | Astro Calculators | Precession tool | Elementary astronomy |

Although most of these formulae and values where gathered from many sources, there are a few books that I have used widely and that therefore deserve credit:

- Astrophysical Quantities
- P. Schwering's thesis
