STAR Database Entries Used in FTPC Reconstruction
In the reconstruction of the FTPC tracks, the run time barometric pressure
and FTPC gas temperatures are used to adjust the drift maps. This information,
along with the other run time condition information, is collected and
archived on sc3.starp.bnl.gov during the run by slow control. Each entry in
the slow control archiver has a timestamp. These timestamps are in local time,
i.e. BNL time = EST.
run time information used in the FTPC reconstruction:
cu_tpc_gas_PT-B - barometric pressure in STAR hall in mbar
ftpc_hdlc:t_gas_1.D [] - FTPC West gas out temperature in degree C
ftpc_hdlc:t_gas_2.D [] - FTPC East gas out temperature in degree C
This information is transferred to the online database on onlsun1. In the
online database the slow control timestamps are saved in GMT.
