SPA-LEED Software Tools

Hier finden sich SPA-LEED Tools und andere im Institut für Festkörperphysik der Universität Hannover und in der AG Horn-von Hoegen entwickelte Programme, die den Umgang mit SPA-LEED Messdaten erleichtern sollen, bzw. bei der Auswertung behilflich sein sollen. Diese Tools werden kostenlos zur Verfügung gestellt.

Es wird für die Funktion und Fehlerfreiheit keine Gewähr übernommen.

Standard Konversions- und Print-Tools

This is a list of some utilities used in combination with the SPA-LEED software. Mainly these programs are used to extract data out of the special formats of the SPA-LEED package ( .D1D, .D2D, .OSZ) or to produce a printout of data in overview.

A zip file with all tools can also be downloaded here

Some of the tools also require postscript headers, which can be downloaded here

D2D2SHT

d2d2sht.zip

D2D2SHT converts a 2D-scan (*.d2d) into a kind of raw data (*.sht) ; format of output-file is the following:

byte 
0..1	nx, number of points in x as a SHORT 
2..3	ny, number of points in y as a SHORT 
4..	data of the 2D-scan as SHORT, nx*ny values

SHORT format is like in C, in pascal it is the type integer. The data is the original number of counts, measured during the gatetime.

Syntax: D2D2SHT inputfile outputfile

Filenames are names with extensions.

Example: D2D2SHT SI7x7.D2d TEST1.SHT

SHT2D2D

sht2d2d.zip

SHT2D2D Converts vice versa from *.sht to *.d2d. Values for energy, length of the scan, x0, y0, … are set to arbitrary values.

Syntax: SHT2D2D inputfile outputfile

Filenames are names with extensions

Example: SHTD2D TEST1.SHT TEST1.D2D

OSZ2ASC

osz2asc.zip

OSZ2ASC Converts a *.osz file taken during autoscan into an ascii-format for a specified packet number.

Syntax: OSZ2ASC inputfile outputfile packetnumber

Filenames are with extensions, packetnumber is 1 to 4.

Example: OSZ2ASC ..\DATA\MBE1.OSZ ..\ASC\MBE1_1.ASC 1

extracts information from point and beamfinder measurements of packet 1 to ascii.

Autoscale

autoscal.zip

AUTOSCALE Scales 1D-scans to their minimum and maximum-values. Values are stored in CPSLOW and CPSHIGH.

Syntax: AUTOSCALE file-specifier

file-specifier need to be given without the extension .D1D

Example: AUTOSCALE TEST*

Scales all 1D-scan-files beginning with TEST, e.g. TEST1.D1D, TEST345.D1D, TESTTEST.D1D …

Doscale

doscale.zip

DOSCALE Scales specified 1D-scan-files from a file-list to given CPSLOW and CPSHIGH values.

Syntax 1: DOSCALE list-file

generates a list-file of all *.D1D from the current directory. The list constists of the full path of the *.D1D-file, the cpslow and cpshigh value, all seperated by spaces.

Syntax 2: DOSCALE list-file cpslow cpshigh

scales all files listed in list-file to the cpslow and cpshigh values.

Example: DOSCALE list.txt

generates list.txt

Example: DOSCALE list.txt 100 100000

scales all file named in list.txt to cpslow=100 and cpshigh=100000.

DoPS1D

dops1d.zip

DOPS1D Creates postscript-output from 1D scans like the SPALEED-Program, but in a quite comfortable way.

Syntax: DOPS1D -pfile -iinputfile -ooutputfile -nnumber -f+/- -k+/- -l+/- -ssensitivity

p parameterfile     contains the standard parameter. 
i inputfile	    contains the names of the d1d files to be printed. 
                    filenames can be given by full path, extension is necessary! 
o outputfile	    filename of outputfile, five letters only 
n number	    number of 1d-scans per page. 
s sensitivity       sensitivity for kparallel scaling. 
f +/-               display fwhm. 
k +/-               axes in %BZ. 
l +/-               display in lin or log mode. 

Example: DOPS1D -ilist.txt -odata01 -n6 -s28.0 -f+ -k+ -l-

DoPS2D

dops2d.zip

DOPS2D Creates postscript-output from 2D scans like the SPALEED-Program, but in a quite comfortable way.

Syntax: DOPS1D -pfile -iinputfile -ooutputfile -nnumber -f+/- -k+/- -l+/- -ssensitivity

p parameterfile  contains the standard parameter. 
i inputfile      contains the names of the d2d files to be printed. filenames can be given by full path, extension is necessary! 
o outputfile     filename of outputfile, five letters only 
n number         number of 1d-scans per page. 
s sensitivity    sensitivity for kparallel scaling. 
k +/-            axes in %BZ. 
l +/-            display in lin or log mode. 

Example: DOPS2D -ilist.txt -odata02 -n16 -s28.0 -k+ -l-

WinStar

starwin.zip

Eine Windows-Version des STAR Programmes

Für k-senkrecht Scans (Heringplots)

Mit dem Programm “whering.exe” können bis zu 400 1D-SPA-LEED Scans komfortabel unter Windows zu einem Graustufenbild zusammengesetzt werden. Dies erweist sich z.B. nützlich bei 1D-Messungen während des “Aufdampfens”. Es lassen sich aber auch Scans bei unterschiedlichen Energien zusammensetzen und so direkt Schnitte im reziproken Raum generieren.

  • Whering 16 Bit Windows-Programm (win 3.11)
  • Whering32 32 Bit Windows-Programm (win NT, Win 95, 98, XP)

Die 32-Bit Version ist aktueller während die 16 Bit Version nur noch aus Kompatibilitätsgründen verfügbar ist.
