General The Emapwin Eclipse simulation software has the following main features. 1) Display of the Eclipse Map The Emapwin calculates draw the following lines on the map. 1) Curve of the central line of the umbra 2) Curve of the northern and southern limit of the umbra 3) Curve of the northern and southern limit of the penumbra 4) Curve of the rising and setting 5) Curve of the maximum eclipse at sunrise and sunset 6) Curve of the maximum eclipse 7) Curve of the equal magnitude The map can be magnified to display the detail of the eclipse. The several parameters such as saros number, time and place of the maximum Eclipse also indicated on the map. 2) Display of the table of the Central line The Emapwin makes a table indicates the northern, central and southern limit of the total or annular eclipse by the parameter of the longitude. So it is easy to draw the line on the map. 3) Display of the Local Circumstance The Emapwin calculate the local circumstance such as maximum magnitude, time , altitude of the sun and direction at the given place. The Emapwin also simulate and display the eclipse at the given place. 4) Display of the Sky at Max. Magnitude The Emapwin display the Sky view at maximum magnitude if that point is in the area of the total eclipse. The Emapwin calculates based on the Bessel elements attached with the software. In the basic release, the Bessel element for all eclipses form year 1951 to 2200 are provided with some famous eclipses in the ancient time. The Bessel elements for the eclipse from 3000BC to 3000AD can be downloaded from my Home page(http://www2c.biglobe.ne.jp/~takesako). The data format of the Bessel elements is same as the Bessel elements of "ELEMENTS OF SOLAR ECLIPSES:1951-2200" by J. Meeus(1989,Willmann-Bell,Inc.). When you use that file delete the header and change the file name to "ECAD22.PRN". The Emapwin is based on the Gmap(Earth Globe draw software) made by Mr. C. Wakaura. 1.1 Recommended hardware and software for Emapwin 1) The Development Hardware : Gateway2000 P5-200 Software : Microsoft Visual C++ Version 6.0(Japanes version) OS : Windows95 2) Recommended Hardware and software Hardware : Pentium 200MHz or more OS : Windows95 Display Mode : 1024x 768 1.2 Version up information 1.2.1 The improved point from the Version 1.01 1) Bessel elements The Bessel elements are recalculated based on the DE406 JPL Ephemeredes. 2) Delta T The delta T is based on"HISTRICAL ECLIPSES AND EARTH'S ROTATION" by F.R.STEPHENSON. 3) The Sky view If the observation point is within the total eclipse area, the Sky view at The Maximum eclipse can be displayed. 4) Saros number The minus saros number is applied for the ancient eclipse based on the "CANON OF SOLAR ECLIPSES(-2003 to 2526)" by H.MUCKE and J.MEEUS 1.2.2 The improved point from the Version 1.11 1) MAP The new version can display the map with the CIA world databak II data which is placed in the following ftp site ftp://ftp.uu.net/graphics/maps/WorldMap.tar.Z-split 2) City Name The city name will be displayed on the map when the enlargement magnitude is more than 20.

Hasegawa"Introduction of the astronomical Calculation" 4.5 Calculation method for Central line with parameter of longitude The Central line and northern/southern limit of total eclipse are Calculated based on the following method. Calculation Method: J.MEEUS "ELEMENTS OF SOLAR ECLIPSES:1951-2200" 4.6 Delta T The delta used in the Emapwin is mainly based on the value introduced by F.R.STEPHENSON. 1) From year 1620 to 2000 The Delta T is calculated based on the table in the "ASTRONOMICAL ALMANAC". 2) Before year 1620 2-1)Between 1620 and -500 The Delta T is from table 14.1 of the "HISTRICAL ECLIPSES AND EARTH'S ROTATION"(1997) by F.R.STEPHENSON.(4) 2-2) Before -500 The Delta T is calculated based on the figure 14.7 of the "HISTRICAL ECLIPSES AND EARTH'S ROTATION"(1997) by F.R.STEPHENSON.(4) LOD(change of the mean solar day) is as follows. LOD=-1.7*(1830-year)/100+(4.3*SIN((1785-year)/1485*2*3.14159265)-0.8) The equation of the Delta T of the previous version is as follows. 1620 > Year >= 948 : 50.6 + 67.50*t + 22.5*t*t (1) 948 > Year >= -175 : 2715.6 + 573.36*t + 46.5*t*t (2) -175 > Year : 1078.3 + 341.5*t + 39.3*t*t (3) The delta T for each case as follows. year (1) (2) (3) (4) 1600 140.6 1166.2 341.1 110 1400 455.6 949.4 444.1 300 1200 950.6 1104.7 861.5 750 1000 1625.6 1632.0 1593.3 1600 800 2480.6 2531.3 2639.5 3000 600 3515.6 3802.6 4000.1 4700 400 4730.6 5445.8 5675.1 6700 200 6125.6 7461.1 7664.5 8600 0 7700.6 9848.4 9968.3 10600 -200 9455.6 12607.7 12586.5 12800 -400 11390.6 15739.0 15519.1 15300 -600 13505.6 19242.2 18766.1 18630 -800 15800.6 23117.5 22327.5 21820 -1000 18275.6 27364.8 26203.3 25550 -1200 20930.6 31984.1 30393.5 29350 -1400 23765.6 36975.4 34898.1 33150 -1600 26780.6 42338.6 39717.1 37050 -1800 29975.6 48073.9 44850.5 41240 -2000 33350.6 54181.2 50298.3 45890 -2200 36905.6 60660.5 56060.5 51030 -2400 40640.6 67511.8 62137.1 56520 -2600 44555.6 74735.0 68528.1 62150 -2800 48650.6 82330.3 75233.5 67790 -3000 52925.6 90297.6 82253.3 73470 3) After year 2000 The LOD(change of the mean solar day) is calculated based on the figure 14.7 of the F.R.STEPHENSON's book and current Delta T value(3). LOD=-1.7*(1830-year)/100+(4.3*SIN((1900-year)/1485*2*3.14159265)-0.8) The equation of the Delta T of the previous version is as follows. Year >= 2307 : 25.5*(year-1800)*(year-1800)/10000 = 102.0 + 102.0*t + 25.5*t*t (1) 2307 > Year : 64.7 + 86.8*t + 34.4*t*t (2) year (1) (2) (3) 2000 102.0 64.7 64.7 2200 408.0 375.9 230 2400 918.0 962.3 570 2600 1632.0 1823.9 1290 2800 2550.0 2960.7 2500 3000 3672.0 4372.7 4160 4) Delta T for Moon's position calculation Because the DE406 uses around -26"/cy2 tidal value, no adjustment is made. 4.7 The characteristics of the Emapwin J.MEEUS compared gamma value of his calculation with OPPOLZER's "Cannon" in his "CANON OF SOLAR ECLIPSES(1898-2510) ".
