Files listing problematic sensors

How to read the files:
The tables are automatically generated in .txt format by a PVSS program reading data from the DataBase. Generation time is included in the file name and the tables contain a list of potential problems found at that time. For each file the sectors scanned are explicitly indicated.
Potential problem are defined as follow:
- No data: Chambers with no entries in the DataBase during the last 5 minutes are listed. Explicit indication (dead chamber) is reported in the Comment field of the table in case of known problems (according to R. Hart's table
)
- Sensor not responding: Single sensors with no entries in the DataBase during the last 5 minutes and belonging to a chamber with at least one responding sensor
- Temperature:
- A temperature is defined as abnormal if it is out of the interval [15-28] C
- A temperature equal to zero is treated as a special case
- Bfield:
- A rough indication of the measured B-field is given using a fixed calibration factor and considering as abnormal values of B>100 gauss (with magnet off). This is not a strict limit, but values much higher must be considered as suspicious.
- A B-field component equal to zero is considered suspicious and treated as a special case
