The Data Info Tab

Data Info tab.

The Data Info tab contains all important information about the work units currently processed. This includes:

From The position in the sky this work unit was recorded. You can get a graphical representation by clicking the Skymap button at the bottom left. More details about the Skymap window can be found in the section called “The Skymap Window”.

Recorded On The date and time the work unit was recorded. The time is given in GMT.

Source The radio telescope that recorded the work unit.

Base Frequency The base frequency of the work unit. The raw data used for SETI@home covers a 2.5 MHz band. To break it down into more manageable chunks, it is split into 256 subbands. Each of these subbands has a lowest frequency referred to as the Base Frequency.

Angle Range Depending on the slew rate of the telescope, each work unit has a unique angle range of sky coverage. The client determines on the basis of this value how much work is to be done with the corresponding WU.

TeraFlops The amount of floating point operations required to process the work unit (given in TeraFlops = 10^12 Flops). The calculation of this value is based on the research done by Roelof Engelbrecht and Lawrence Kirby.
