// Sun Outage Predictor
// Predicts sun outages for any satellite and ground station
// December 10, 1997
//
// Original Excel Macro developed by Hughes Communications Inc, Orbital Operations
//      Orignal Concept and number crunching by Mark Shannon
// Orignal Excel Spreadsheet Macro design by Miro Svetinsky
//      Conversion to JavaScript by Michael Shoffeitt for iXL, inc.  mshoffeitt@ixl.com
//
//
// Note that most of these variables and formulas were named based upon the names they were given orginally in the
// Excel Macro - Hence some are named '<Col><Row>' as in 'F6' based upon the cell names from the Excel Macro...

// changes to calculator made by:
// schupp
// 031799
// with the help of Mark Shannon
//
// corrections for azimuth and elevation..
// corrections to Smartround()
// display of year in 'yyyy' format where it appears
// extra comments..
//
// who ever works on this next, the current version of the .xls spreadsheet
// that this is taken from is: 'SunOutage Predicter 2.2.xls'
// you will want to get a copy of it.
//
// also, there seems to be a bug in atan2(x,y)
// the true implementation of it: atan2(y,x)
// (as of javascript 1.2)
//
// this may be the cause of erratic results in the future
// -s
//
//
// Modifictions made by Jens T. Satre jensts(a)online<dot>no to make the outage predictor not dependant on 
// the document forms . Also added posibility for correcting results for inclination/ satellite latitude
//
