Software, by Bob Nelson

All of this is is freeware; use as you wish.  For Windows platforms only (sorry Linux, Mac).

Astronomy Software

Routine

Vers. Date

Description

 Astrotime 42 2012-07-24

A utility that converts epochs, calculates HJD, horizon coordinates, and more.  Now does sunrise and set.

Broadening Functions

26 2013-11-25

The Rucinski routines to derive RVs from stellar spectra.

 Clear Skies 13a 2005-11-11

Saves Clear Sky Clock values to file.  Source code using WebBrowser is useful example.

 EB Min 21 2012-07-24

Generates predictions of EB minima for your date, location, and local horizon.

 Minima 25c 2007-05-10

Finds the precise times of minima for eclipsing binary (EB) data using 6 methods.

 B_Minima 12 2005-05-18

As above but handles huge files in batch mode (it searches for minima automatically).

Period Search

15f 2006-07-12

Finds periods for EBs based on portions of light curves.

 Phases 14b 2012-07-24

Prints out, for a given night, the phases of various eclipsing binaries for each hour (visible at your location).  Very effective.

 RaVeRe 22c 2012-07-24

Does intermediate processing for spectral image files (and saves a ton of time over IRAF!!)

 Sp_Analysis 14 2007-05-10

Displays up to 10 spectra (with offsets adjustable), reads wavelengths under cursor, etc. [More features to come]

 Tables2Tex 10f 2005-10-31

Converts text files with tables to Tex format.  (It's great for IBVS publications!)

 TomCat 17e 2007-05-10

Finds periods for EBs based on times of minima.  (It's hot!!)

 VHLimb 1.1 1994-05-20  Program by Dr. Dirk Terrell that interpolates the van Hamme limb darkening tables
 WDwint 56a 2009-06-27

A front end interface for the Wilson-Devinney star modelling package.  This upgrade has additional help and error traps.

Physics Software

All of these programs are DOS-based.  If there is interest in more modern Windows-based versions, please contact me at the address below and I'll see what I can do.

Routine

Vers. Date

Description

 Eq_Pot 45 1992-06-19

A routine that plots equipotential and electric field lines for electrodes that you draw.

Funcs

55 1992-05-02

A number of physics functions (e.g., SHM, Planck, Maxwell, Fresnel diffraction, QM square well wave functions).

 Trajec 26 1992-06-23

Plots real trajectories in air for a number of common projectiles (e.g., baseballs, ping-pong balls, etc.).  The effect of wind is allowed for.
