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:

1. 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)
2. 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
3. Temperature:
   1. A temperature is defined as abnormal if it is out of the interval [15-28] C
   2. A temperature equal to zero is treated as a special case
4. Bfield:
   1. 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.
   2. A B-field component equal to zero is considered suspicious and treated as a special case
