could you give us some hints how the ALFA data differ from the current data, and how this effects the analysis.

Hi Hans,

Sorry for the late reply. You may have seen in another thread that I'm out of town. I've got time to reply today because my wife is having a bout of food poisoning.

The main issues that will be resolved in the first release are identifying which of the 14 data streams (7 beams, 2 polarizations each) the data comes from. There are also some issues with making sure that the differences in beam size are handled properly. There are also a significant number of changes to the splitter required to make work units from the new data, since the tape format is very different, and the algorithm used to calculate coordinates has some additional steps.

The second multi-beam release will need to be able to handle cases where the receiver steps in frequency in the middle of the work unit. (The new data recorder has the ability to cover a wider frequency band by chaning the recorder central frequency.)

This message isn't exactly relevant but might apply if one is sick enough, and it applies to anyone. I can't remember the last time I've thrown up. When I cook my food I always take it to boiling (99C at my location) and don't own a microwave which doesn't heat every bit of the food that's put in there. When I process raw meat I keep it isolated from any food that I don't cook before eating and any plate/utensil that will contact that food. I also wash my hands with bleach and detergent if I handle raw meat. Back when I was a kid, about 50 years ago, about every six months my stomach ached and I often threw up. If I ever find a suitable girl or woman (I probably never will) I'll have to change some of her habits so she and I won't throw up.
