1 Initialization
In the program version V7.2.03, the Help files are new.
Create one folder titled "_help" after unzipping
the program, and move the Help files. In V7.2.02,this step is necessary.
(In V7.2.01, this step is unnecessary.)
*Note* ---The first character in "_help" is an underscore.
The texture files in the directory "_textures" you need for texturing
planetary moons in Ehpemerides/Graphics.
(V7.2.04)
The selection window of the planets opens when the program is started for the first time.
Select "Jupiter (1)".
(V7.2.03)
Click the icon of the program and the WinJUPOS screen opens.
Choose "English(2)" from"Language" in the drop down list. The default language is German.
*Note* ---The red sections in the English help file are not translated sections
from the German (original) version.
(V7.2.03)
2 Importing images
2.1 Choose "Image measurement(3)" from the drop down list under "Recording".
(V7.2.03)
2.2 Click "Open image(4)". And the image is uploaded.
2.3 Input the observation date and time in UT.
Input the longitude of the observation site (East longitude is +)
and the latitude (North latitude is +). (5)
(V7.2.03)
---The date and time (UT) are used for CM calculation.
---Longitude and latitude are important for tropocentric co-ordinates and times for set and rise.
These values have no effect for C.M. latitudes of Jupiter.
2.4 Click the "Adjust(6)" tab.
2.5 Click"Automatic(7)," and the outline and equator of Jupiter are displayed.
---Perform the keyboard operations (as written in the figure) when adjusting the position
of the circle by hand.
2.6 Choose the"Image(8)" tab, and save the image data.
The image data file is created in .ims format.
(V7.2.03)
Keyboard operation when the position of the circle is adjusted by hand
Arrow keys ---direction buttons for moving the outline
PgUp ---increases the size of the outline
PgDn ---decreases the size of the outline
N --- rotates the outline clockwise
P --- rotates the outline counterclockwise
Backspace --- rotates the outline by 180 degrees
Case of the south top image
Before 2.4 please choose the principle adjustment of the outline frame.
If south is top at your image rotate the outline frame in this way,
that "N" symbol is at bottom. Otherwise rotate "N" to top. Use the key
[Backspace] for this rotation (rotation of outline frame by 180 degrees).
*NOTE*---It is not the same result if you press
a) [F11] and then [Backspace] and
b) first [Backspace] and then [F11]
The background of this phenomenon is the limb darkening of the planets ellipse.
Case of the more than one planets images in one file
It is also possible to use the "Automatic adjustment" if you have more than one planetary images
in one file. In this case please decrease the Measurement window or zoom and move the image in
this way that you only see one full planetary body. After that press [F11].
3 Positional measurement of planetary features
3.1 Select the "Pos.(9)" tab under "Measurement of (Jupiter) images."
(V7.2.03)
3.2 Choose the cross-wire type under "Type(10)".
There are four kinds cross-wire and outline types
(large cross-wire, small cross-wire, large cross-wire with an outline,
small cross-wire with an outline).
3.3 You can measure the position by matching up the cross-wire directly with the planetary feature.(11)
(V7.2.03)
4 Making drift charts
4.1 Preparation
4.1.1 Decide the method for arranging the record of the measurement data.
---Method of creating measurement data files for each observer.
It is highly recommended to use only "Method of creating measurement
data files for each observer.Every observer gets one Measurement file (*.mea)
4.1.2 Creating a project folder
---Create a folder that contains the measurement data.
Two or more measurement data files are placed in the same folder.
---Create a folder at the output destination for the drift chart.
Hahn's directory structure is:
D:\WinJUPOS
\_help
\_textures
\Jupiter
\Images
\2005 (date-observer name-info.jpg)
\2006 (date-observer name-info.jpg)
\Measurements (observer name.mea)
\Central Meridian timings (observer name.cmt)
\Selections (object name-info.wse)
\_Settings
\Image Measurements (*.ims)
\Selections (*.ses)
\Drift charts (*.grs)
\Map computations (*.mcs)
\Image computations (*.ics)
\Drift charts (*.gif)
\Maps (*.jpg)
\Saturn
...
\Uranus
...
|
*NOTE* --- For international data exchanging I highly recommend to use only pure ASCII
characters (= English) for directory and file names, observer names and addresses,
image info. But you do not need it, if you use the data only in your own country.
4.2 Creating and initialization of measurement data files
4.2.1 Start WinJUPOS.
4.2.2 Select "Measurements/New(12)" from the drop down list under "Recording." Enter the file name.(13)
(V7.2.03)
(V7.2.03)
4.2.3 A new file is opened, and initial screen(14) is displayed.
4.2.4 Input the "Date(15)".
(V7.2.03)
4.2.5 Click the "File button(16)", and select "Info(17)" from the drop down list.
(V7.2.03)
4.2.6 Type the "Observer name" and"Address".(18)
---You will type the latitude and longitude of the address, e-mail address,
and the observation location.
---You can edit these data at every time if you open the Measurement file
via "Recording - Measurements/New..."
(V7.2.03)
Exsample
Toshihiko Ikemura gets the file "Ikemura.mea"
The "Observer name" is "Ikemura, Toshihiko"
The "Address" is "Nagoya City, J"
All observations / object positions of Toshihiko Ikemura will be stored in "Ikemura.mea".
4.3 Recording of measurement data
4.3.1 Select "Image measurement" in the drop down list under "Recording".
(The image processed immediately before is displayed. )
4.3.2 Follow the steps in "2 Importing images" and "3 Positional measurement of planetary features"
when you measure a new image.
4.3.3 Select the "Pos.(19)" tab, the measurement screen is displayed.
4.3.4 Match the cross-wire(20) on planetary feature and click. Click "Save object position button (a) ".
(V7.2.03)
4.3.5 The window (b) of the data input appears.
Input the observation pattern type in the column for"Code (c)."
(See the explanation in the following section 4.3.7.)
(A question mark sign "_" is displayed in the column for"Code." This"_" is a delimiter.)
4.3.6 Click the "Save (d) " button. Then, the record of the measurement data is added.

(V7.2.04)
4.3.7 Concerning the input for the"Code" column
---Ahead of the question mark sign "_"
1st letter : W-- for a bright object,
D-- for a dark object,
2nd letter : P-- preceding side,
C-- centre,
F-- following side,
3rd letter : 1-- if the object was easy,
2-- if the object was moderate,
3-- if the object was difficult to see (in case this information is available)
---After the question mark sign "_"
Bright object : SPTR, ASPOT, OVAL, BAY, NICK, GAP, SECT, RIFT, AREA, STRK
Dark object : SDER, SPOT, BAR, FEST, PROJ, SECT, VEIL, DIST,COL, STRK
Look at the Object code Jupiter (JUPOS) in the Image measurement Help section,
if you want to know in detail.
*NOTE*--- Your "Measurer code" you get from Hans-Joerg Mettig/Germany, if you want to measure
object positions for the international WinJUPOS database.

The texture maps for the planets can be downloaded from the NASA website or the website
of James Hastings beforehand. (These are linked from Grischa Hahn's website. )
For the texture maps from NASA, the longitude on the edge is 180 degrees.
For the texture maps from James Hasting's website, the longitude on the edge is 0 degrees.
