IBS sweep table prior to December 2003
IBS sweep table December 2003 to present
IBS counts start at 1 (not 0) in both the Binary and CDF files
Problems in the data files
1) According to Frank and Co. the IBS data may be scrambled every now and then.
2) Time stamp not in time order.
Example: for 2004019 hour 9-10
TIME BCYC ACYC 09:09:58 114 1032 then 09:14:14 120 1040 then back to 09:10:30 114 1033 09:11:02 114 1034 09:11:34 114 1035 09:12:06 119 1036 09:12:38 115 1037 09:13:10 115 1038 09:13:42 115 1039 Then jumps to 09:14:46 116 1041 09:15:18 116 10423) also note bcycle in and out of sequnce as well.
Questions not resolved:
1) Wording in CAPS Archive SIS for IBS mode/submode incorrect for Magnetosphere. Says Track but should be Survey.
2) In solar wind track mode 256az are broken up into two sweeps of 128 az.
3) Not sure where to get DPU_Acquire =normal or =solarwind.

Plots for IBS are not high resolution. Data collected only from every other sweep in track mode. And plotted for both track and search mode at rate of 132sec averaged. This was done intentionaly, according to Frank.
There are two sources for actuator data, 1) the actuator data product and 2) the a-cycle header. The actuator data product is produced in 16, 8, 4 and 2 kbps now. 1, 0.5 and 0.25 do not have the actuator data product. In all cases the actuator data is recorded in the a-cycle header. The ground system will take actuator data from the A-cycle header for 1, 0.5 and 0.25 rates. There are 4 values in the a-cycle header, sampled every 8 seconds. When we do get an ACT data product, it contains 32 samples, one every second.
