• Conversion between degrees and hours, sexagesimal and decimal.
• Equivalence between measures of distance, including astronomical scales (Astronomical Unit, Light Year and Parsec).
• Conversion amidst Kelvin, Celsius and Fahrenheit temperature measuring scales. Considering humidity values you can also calculate the condensation point.

Lets you write down the trajectory, magnitude, speed and number of observed meteors; date and hour of the event; stream to which it belongs; observer's name and place of observation. The point is to later extract this info to a database.

Main features include: customizable gamma presets - you can create and save your own; high-resolution sliders allow you to adjust red, green, and blue video components individually and in real time; "Bailout" assignable shortcut keys offer a quick return to full brightness.

Designed around Release 9.0 of The Arizona Database of deep-sky objects, contains data and information on over 61,100 deep sky object.

Other features included are: an editable observing list; a Moon explorer tool which describes craters and points their location on a picture; a solar system orrey; a Moon phase and position table calculator for a chosen range of time; and a Jovian system simulator.

In order to calculate atmospheric trajectory and orbit of meteoroids, Fireball needs:

1- Data and hour (Universal Time) of the observed fireball
2- Geographical location of two observer that observed the same fireball
3- Equatorial coordinates of two trajectory points from observer number 1
4- Equatorial coordinates of two trajectory points (not the same of observer 1) from observer number 2
5- Duration of the fireball from the two observers

Press the button <Trajectory> to calculate atmospheric trajectory. The file "Trajectory.txt", with all the data, will be written in the Fireball folder. The most important data are written also at the bottom of the window dialog.

Check the resulting mean velocity value. If you want an orbit for this velocity value press the button <Orbit> otherwise put a new value and press. The file "Orbit.txt" with all the data will be written in the Fireball folder.

Correction applied to atmospheric velocity to obtain eliocentric value:
- Earth's rotation
- Diurnal aberration
- Terrestrial gravitation
- Earth's orbital motion

Features include:

• Programs for fast simulation and analysis of full-sky maps of CMB temperature and polarisation anisotropy up to sub-arcminute angular resolution (your computer's RAM permitting).
• Routines to read and write the FITS formatted map data sets, and allowing the IDL-based display of your results.
• Programs to search the maps for pixel neighbours and extrema of a random field.
• Automated installation and build scripts.
• Improved Fortan 90 programming standard.
• Optimised P_lm recursion for better performance (about 20 percent faster).
• Radek Stompor's P_lm recursion accurate for computations up to l = 10000.
• A constrained realisation facility.
• Improved IDL display and file handling routines.
• An IDL toolkit for pixel manipulation and FITS file manipulation.
• A Fortran90 MAP2GIF visualisation facility.
• Improved documentation.

The viewers themselves are rather small in size (around 300 Kb) but you will need to separatly get the data sets from NASA/GSFC.

Standard program options include: Auto Despeckle - fill random missing pixels and correct bad pixels (salt and pepper effect); Auto Reconstruction - fill systematic missing pixels (max. 75% missing pixels) ; Auto Contrast Stretch; Auto Flip Vertically; Auto Invert Display; Auto Sharpen; Auto Minimize ( 50% original image); Auto Scan - scan pause options (2,3,4,5 seconds)

Buttons: Next and Previous image buttons; Scan Forward button; Scan Backword button; Scan Stop button; Restore Original Image button; Despeckle on/off button; Reconstruction on/off button; Contrast Stretch on/off button; Flip Vertically on/off button; Sharpen on/off button; Invert Display on/off button; Minimize on/off button; Brightness up/down buttons; Contrast up/down buttons; Brightness gradient reduction buttons; Info Image button.
