Component for a data block Component for a data block manipulation and creating FITS filesmanipulation and creating FITS files

It will be a program (resp. a set of programs) with no GUI and its main It will be a program (resp. a set of programs) with no GUI and its main purpose is to generate FITS files and store them to a databasepurpose is to generate FITS files and store them to a database

this program this program willwill run on a server in Wroclaw or, in case the server in run on a server in Wroclaw or, in case the server in Wroclaw does not run, it Wroclaw does not run, it willwill run on a server in Ondřejov run on a server in Ondřejov

Because of this, part of this program is a watchdog which will check Because of this, part of this program is a watchdog which will check whether instance on the other machine is running or notwhether instance on the other machine is running or not

First part called „First part called „Data blocks transfer componentData blocks transfer component“ will download data blocks “ will download data blocks (raw files(raw files)) from FIAN data server and distribute them for further processing from FIAN data server and distribute them for further processing
