-Since July 2010 a new antenna control and observing software is used at the Effelsberg 100m telescope. The interface for the observer is still called "​OBSINP"​, like the old system, but it is now a graphical based control program. It allows the control of all observing modes possible at the Effelsberg antenna. This document gives a brief introduction to all the different sections in OBSINP for each observing mode. More details on how to set up and organize observations of different types are given in the individual sections of the [[information_for_astronomers:​user_guide:​index#​observing_with_effelsberg|User Guide]].+Since July 2010 a new antenna control and observing software is used at the Effelsberg 100m telescope.

 All observations are stored and organized by a queue system that allows to prepare the next steps during your current observations are in progress. It also allow to prepare observations in advance for later processing at the telescope. The structure of the program is shown in Fig. 1. All observations are stored and organized by a queue system that allows to prepare the next steps during your current observations are in progress.

-The Startup widget is the first screen that appears when you call OBSINP and should be filled with the information that is requested: Operator, Observer, Project-Code,​ and the working directory. The observers directory will contain the folders for his own catalogues and scripts. The directories are called Catalogues and Scripts and will be created by the system if not already existing. \\  The new catalogue ​format is somewhat ​cryptic and therefore it is recommended ​to just convert ​your old VAX-catalogues using catalog.py. ​A new catalogue preparation tool is planedThe preparation of scripts is described later in the Pointing ​and Spectroscopy sections.+The Startup widget is the first screen that appears when you call OBSINP and should be filled with the information that is requested: Operator, Observer, Project-Code,​ and the working directory.

 +==== Catalogs ==== 
 + 
 +With the new Obsinp observing software, source catalog files are stored in the SDB (structured data base) format. This format is somewhat ​less easy 
 +to understand as the (old) VAX source catalogs. However, there exists a script ''​catalog.py'',​ which can be used to convert ​files having the old VAX format to the new Obsinp format. Using 
 + 
 +<​code>​catalog.py ​sources.cat</​code>​ 
 + 
 +on the **observer2** computer will create a file ''​sources.sdb''​. If you place it into ''/​home/​obseff/​your_obs_directory/​Catalogues''​ it will be found automatically by Obsinp (if you choose the correct startup directory). 
 + 
 +For the preparation of your observations we recommend to prepare a catalog ​in the [[:​vax_catalog|VAX format]] ​and convert it into the new format afterwards. 
 + 
 +Alternatively,​ you might use our catalog tool for creating and editing catalogs, see [[:​information_for_astronomers:​user_guide:​pycatalog]].
