AAVSO Software
The software listed here may be downloaded for free. The data entry software helps you prepare
your observations in the official
AAVSO format. Use KSOLO, PCObs, or
spreadsheets to prepare and properly format your observations (or just use WebObs to submit observations automatically over the web
in the correct format).
The data analysis software may be used to analyze the data in the AAVSO International Database. Plot
and analyze AAVSO formatted observations using ZAP or perform statistical time series and wavelet analysis
with TS and WWZ. If you have any questions please feel free to contact us.
Data Entry Software
- PCObs 3.0 Release date: January 2008
- A Windows point-and-click interface that
automatically formats your observations into the official
AAVSO format.
- Excel Spreadsheet
- This Excel spreadsheet will take visual observations submitted in the BAAVSS
format and also export them in VS-Net and the new AAVSO formats. Special thanks to
Gary Poyner for providing this spreadsheet to the public.
- CONVERTV.EXE
- A program that converts VSNET format
observations to
AAVSO format observations
- ZA-VSTAR.ZIP - (PC program & Pascal
source
code)
ZA-VSTAR.TXT - (Readme File)
- This is an
observation planning tool that will search the AAVSO validation file for objects that meet criteria based on
magnitude, declination, and right ascension. This is donated by Zeljko Andreic and not officially supported
by the AAVSO. Read the Readme file for information on contacting the author.
- OBSVAR V1.5 - Link to web page
by Laurent Corp
OBSVAR.TXT - (Readme file) - This is a link to an
observation planning tool created by Laurent Corp (CLZ). It will search the AAVSO or AFOEV Bulletins and
extract data that meets different criteria such as Constellation, Month, Right Ascension, etc. The web page
is in French and there is an English option available. This software is not officially supported by the
AAVSO and any questions should be directed to the author.
- CLEANest - 3/10/05
- This is Visual Basic source code for the CLEANest and SLICK algorithms in TS. Cleanest is an effective method for removing false peaks from a power spectrum and can also describe and detect
multiperiodic signals. (Foster G., AJ Vol 109, Nr
4, April 1995 "The cleanest Fourier spectrum")
- PhasPlot - 3/10/05
- PhasPlot is a Windows-based tool for plotting phase diagrams of variable star data. The user interface is designed to make it easy to test different periods on a star.
PhasPlot is designed to work with data from the AAVSO International Database downloaded via the official form to download data without any reformatting of the data needed.
- MagPlot -
- Windows software to display and analyse light curves using AAVSO data Release Date: 9/22/04
- TS (Fortran) Release date: 4/6/04, Updated: 10/26/05
- A Fortran based time series statistical program that enables you to analyze variable star data.
- TS (DOS) Version 1.2
- MS-DOS based time series statistical program that enables you to analyze variable star data.
- WWZ (Fortran) Release date: 4/6/04
- A Fortran based time-series analysis program used to study the time-evolution of variable
star data, capable of measuring changes in period, amplitude, and mean
magnitude.
- WinWWZ (Windows VB.Net) Release date: 12/3/04
- A VB.Net based time-series analysis program used to study the time-evolution of variable
star data, capable of measuring changes in period, amplitude, and mean magnitude.
- WWZ and TS Bundle (Fortran) Release date: 4/6/04, Updated: 10/26/05
- Download the Fortran versions of both TS and WWZ all at one time.
Solar Software
- SolObs
- Windows-based observer data entry software
for the solar division. Also includes a new Stonyhurst template
routine. Use this for your reports.
- SPOTPLOT.EXE
- MSDOS Stonyhurst template program.
Draws solar disk for sunspot plotting. Written by Joseph Lawrence
(lawrence@ipfw.edu)
Eclipsing Binary Software
- EBMin23.ZIP
- A DOS program to predict minima
for eclipsing binaries and more. Written by Bob Nelson
(bob.nelson@shaw.ca).
Useful Windows Software
- Software, by Bob Nelson
- Programs range from finding times of minima to intermediate processing of spectral data (no IRAF!)
- Variable Star Telescope Simulator
- A 2.5 Megabyte powerpoint presentation created by Chuck Pullen, AAVSO member, that introduces
you to the AAVSO and shows you how to estimate the magnitude of a variable star.
- Gamma Ray Burst Presentation
- A 3.5 Megabyte powerpoint presentation created by Chuck Pullen, AAVSO member, that introduces
you to Gamma Ray Bursts and the AAVSO Gamma Ray Burst
Network.
- HOAFUN 2.0
- A Windows version of the DOS-based program distributed with Hands-On Astrophysics. This is a great tutorial for making variable star
observations. It has a game, examples, and even prints out an award certificate for completion of the game.
For Windows 95 and up. It was written for junior high through high school but applies to anyone just
beginning variable star observing.
