For all images the principle is

displays the number of echoes counted per hour on a month.
On the horizontal axis every column of pixels represents one day
of the month (left to the right).
On vertical axis every colored
square represents 1hour from 0h UT (in top) to 23h UT (in bottom).
Some hours, days or all the month of observation can be represented.
The black square indicate an absence of observations (for maintenance
It is this image type used on http://www.rmob.org in visual part.
How to use :
You have 4 possibilities for read
3 different files types.
In "Local datas source"
or in "distant datas source" in LIVE
processing you see 4 colorgramme images ( as here, below ).
In the order top to down, left to right :
Image of the COUNT
( Numbering ) of meteor echoes detected while the month.
of the Flux while the month. One good radio installation have only
a small variations of this value. If your station is stable and
at one moment you see some big variations it indicate probably a
sporadic disruptions, or a big meteor shower...
your installation quickly, wait 1 or 2 days, if is an disruption
it length not really very long time.
Image of the Length
of echoes expressed in seconds. Easy to understand.
of the Length of echoes expressed in pixels. Pixel is one point
into your measure window, this is equivalent of the length in seconds,
but the length in seconds is the result of an calculation and this
calculation round the values. One small difference exist !
Max Auto check box :
Uncheck if you want to modify the scale of the images, with the
scroll bar at right of all images. You change the maximum value
allocated at the red color.
Image buttons at right of
all images is useful if you want to save ( in BMP format ) the image
on your hard disk.
Open RMOB File, Open STA File,
Open DAT File buttons :
ATTENTION in this 3 case it UNCHECK
live process !
All buttons is for visualize a special files.
RMOB files is created by all Meteor soft to store monthly
data observations and it is used on http://www.rmob.org
Image of RMOB file is displayed only in top, left corner.
files, is a "old" file format created by Meteor DOS
software. this is at hourly count text files. Colorgramme WMeteor
v 3.3 don't create these files anymore, is replaced by DAT files.
Image of STA file is displayed only in top, left corner.
files, is a new standard of output files from Meteor software.
This files store all datas, count, length, flux come from the soft.
Images of DAT file is displayed in all 4 images as in live process,
but the live process is stopped !
