# Loose Targets

This information is provided by Billy Christie:

```B1V2 (10-187) Prerun comments: No comment Postrun comments: Very Loose
B1V3 (10-141) Prerun comments: Little Loose   Postrun comments: Very Loose
B2H3 (10-200) Prerun comments: No comment Postrun comments: Very Loose
B1V1 (10-168) Prerun comments: Little Loose   Postrun comments: N/a (the target did not survive the run)
```

There are only few measurements with B1V2 and B1V3. No good sweep measurements available with these two targets.

B2H3 indeed may have been giving a non-gaussian intensity profile for sweep measurements [1] [2] [3]

B1V1 was giving nice gaussian intensity profiles most of the times. [4] [5]
