| ILLUSTRATING SHADOWS focusing on education and interesting practical aspects of sundial design FREE Excel SPREADSHEETS Not for Open Office ~ for Open Office, use these *** Try cubicShadows.xls spreadsheet very small, easy, and does most dialling stuff *** |
| FREE ~ DAY SPECIFIC SPREADSHEETS FOR DIALING ~ using PC Excel ~ (try the Palm Pilot Docs To Go versions also, here) Two major spreadsheets for Illustrating Shadows are all in Excel format, the main sheet and the EOT sheet. This general dial spreadsheet (illustrating-shadows.xls) which uses this complete EOT spreadsheet (illustrating-shadows-eot.xls) which has been redesigned (and replaces reference-spreadsheets.xls) and enhanced based on demand. It has many many features. It begins with an index page followed by an almanac page, then a set of detailed pages. Please download both spreadsheets. Note: reference-spreadsheets.xls was renamed illustrating-shadows.xls, however the detailed functionality is unchanged. New stuff includes the astrocompass degree method correction (as opposed to the time method). The wall declination section (and these notes) were totally rewritten and simplified. Also, the front page is much simplified, and more useful, again major cleanup work. Astrolabe degree method enhanced and pictorials added. These sheets work on Vista win64 systems. Other spreadsheets exits for special one off calculator usage. TABLE OF CONTENTS Your latitude: eg 32.75 Your longitude: eg 108.20 Legal meridian longitude: eg 105 Julian day (1-366) eg 253 Astro compass degree method (versus time method) adjustment Almanac page with lots of data, and noon transit table for each day, you add (west) or subtract (east) long diff from legal time meridian. H dial [plus altitude and azimuth], V dial, ...non decliner Ceiling dials V decliner (the standard formula, and also a new derived formula)(with charts) V meridian Polar dial Analemmatic Sunrise-set - EOT mm.ss Sunrise-set EOT decimal Pie charts for hr line angles Reverse engineering an h-dial Legal standard time (not summer time) to sun's hour angle, optionally corrected for longitude and EOT, useful for astro compasses Wall declination (a major simplification and rewrite April 4) Middleton scales Astronomical EOTs (static), which hyperlinks to the general EOT spreadsheet with many formulae including the astronomical version. EOT combined with a longitude shift, useful for generic dials moved from the legal meridian Declining recliners Lunar phases Declination line design aid ~ ~ See Declining Shadows which is a summary, or Illustrating More Shadows which has an in depth discussion, for descriptions of this feature. Analemma curve ~ ~ any latitude and longitude, for any time whatsoever for h-dials (horizontal) at latitude 0 this is a polar dial, and reversing signs and hours, this works for a vertical dial, and by messing with the time while using SD and SH and D.LONG this works for decliners also. There are very few times and latitudes where this doesn't work well, and the spreadsheet makes it easy for you to "tweak" it. Actual formal design latitudes are +0 to +60, times are 08.00 to 16.00 Planispheric astrolabe (matches the DeltaCAD macro, or, see this page here for geometry of the astrolabe) also the ANALEMMA page has spreadsheets for all hour line analemmas. |

| *** NOTE *** these spreadsheets deliberately use several different EOT formulae, and they do not all agree. This is so people can play with different formulae. Just be aware that they differ sometimes by up to a minute. |

| Check the PocketC page also. This has the v-dial, v-dec, and h-dial programs, as well as an almanac and the astro-compass aid. as either complete .prc hot synch files, or as C files for PocketC, your choice. Graphical depictions. |
| The illustrating-shadows.xls spreadsheets have been reworked for PDAs, specifically the PalmPilot. The vertical decliner spreadsheet is shown to the left on a Palm T3. A new vertical decliner sheet and ceiling dials added. Nov 29, 2008 Display output has been reworked, hyperlinks removed and the sheets adapted for their removal, changes in formulae not supported by Documents To Go, size changes, and so on. The h, v, and v-dec dials are supported, three EOT sheets provided, analemmatic, armillary and equatorial dial calendar and hour data supported, calendar curves, and so on. |
| HINT: Just because you don't have a PDA, don't let that stop you from using these PDA spreadsheets. They are simpler than the main PC spreadsheets, and in some cases actually have more options, such as the calendar curves spreadsheet! |
| NOTE: There are more PDA based spreadsheets that work on Excel than these PC based Excel sheets. So, download the PDA sheets as well. |

| Excel A collection of spreadsheets for Microsoft Office on the PDA, do not use these if you use Open Office, use these instead. NOTE: When you start the spreadsheet, no menu of all the other sheets appears UNTIL you enter a Julian day in cell E7. This is to allow you to enter any Julian day, and only when you have selected a Julian day will the rest of the menu appear. If you want change cell from... 0 to.... =e6 |
| Tested on Documents To Go 7.006 and on 10.0020 and the graphics on the Palm are supported, for example in the EOT astro sheet and the figure of 8 analemma sheet. Click the graph button below the spreadsheet cell data entry area. PDA XLS zip file is here. |
| FREE ~ TABULAR SPREADSHEETS FOR DIALING ~ PC Excel ~ (These produce annual tables rather than details for one day) Whereas the two spreadsheets for Illustrating Shadows are all in Excel format (the main sheet and the astronomically accurate EOT sheet) produce full screen detailed information, usually for a specific day or limited range of days, these spreadsheets for tables produce the tables used in the appendices for the Illustrating Shadows series of books. The names are similar to the names and functions of the PDA specific spreadsheets. The ZIP file is here. |
| If you use Open Office, use my open office spreadsheets, and not Excel. There are many subtle differences so Excel sheets with special features do not work in Open Office and vice versa. Please read these notes here that discuss Microsoft Office, Open Office and Documents to Go. |

| However, if you do that, and then enter a specific Julian day other than today, and then save t, you may forget you did that and thus misread results. |
| Added July 11, 2009: reference-X-and-Y-for-an-angle.xls does an X distance given a Y distance and an angle (as a table) and a Y distance given an X distance and an angle (as a table) Added Aug 2, 2009: analemma.xls and Open Office here does an X radius (based on EOT) for a Y distance (based on solar declination) for an EOT bobbin for an armillary dial of a given radius. Notes are here, see also DeltaCAD. Added Aug 9, 2009: DL values have been added back for vertical decliners, helpful for those who want analemmas on vertical decliners. See the analemma notes here, analemma page here. Added Nov 23, 2009 EOT and long.diff combined worksheet Jan 7, 2010 de cluttered main screen, much simplified Jan 15, 2010 New simple spreadsheets added microShadows.ods simpleShadows.ods, and quickShadows.ods and they match the free books Micro Shadows, Simple Shadows, and Cubic Shadows. May 8, 2010 Added what the analemma looks like in the sky |
| NOTE: based on user feedback, cells that should not be changed are now protected. Do ALT-T, P, and choose the "P" unprotect option if you want to change other cell data. |
| The most complex system is Illustrating Shadows.xls which is pictured to the right. |
| THE FOUR Excel SPREADSHEETS INCREASE IN COMPLEXITY microShadows h-dial only (extremely simple) simpleShadows h-dial, simple alt, azi (very simple) quickShadows h,v,v-dec,q,a,p alt, azi (simple) illustrating… all functions (full strength) |
| There are four main spreadsheets, microShadows (and its free book), simpleShadows (and its free book), cubicShadows (and the Cubic Shadows free book), and the main spreadsheet: illustrating-shadows.xls, available in Excel (.xls), Open Office (.ods), and MS Works form (.wks). Each is more complex than the last. Also, illustrating-shadows-eot.xls is very helpful for astronomically accurate EOTs. In fact, cubicShadows is so good it also now in the main spreadsheet as well. |
