S117 RAW Datasets (B Tapes)

The B Tapes with volume labes B04xxx contain a copy of all S117 RAW datasets. The RAW datasets have been copied on consequtive tape volumes such that each tape contains about 10 Gbyte data. Therefore the B tapes are not a simple one-to-one copy of the A Tapes but have a different mapping of run numbers to tape volumes as listed below.

Note, that only B Tapes should be used in offline analysis ! The original A Tapes serve as backup copy and are stored in a save place.

The Runs column of the following table contains a link to a Run list for each tape. The run list is a file with the run numbers in the simple format `one run number per line'. Those run lists are especially useful in DCL scripts and KUIP macros. Keep in mind that sometimes single runs are missing and that one therefore can't use a simple DO loop to generate the run numbers. In case you need to access the Run list in a script or KUIP macros use the name

	kpw_root:[doc.s117.tapes]set_<label>.dat
For an example on how to use them in a KUIP macro see pass0.kumac.

Note, that the B Tapes use a 48 kb physical block size whereas the A Tapes use a 16 kb block size. This is transparent in use but affects I/O overhead. The record size is, of course, for both A and B Tapes 16 kb.
