Titles Files ------------ anxx_pca.dat anxx_n16.dat anxx_neutrino.dat Verification ------------ Description ----------- This bank contains the output from the Abnormal channel analysis processor (ANX), and lists the types of abnormality found for the remaining abnormal channels beyond those tagged by DQXX or failing eca and pca calibrations. Bank Number ----------- n Event data type:- 1 PCA 2 N16 3 Neutrino (Historical note: originally each data type had its own bank name: PCA: ANLB, N16: ANSN, Neutrino: ANNU so collectively, the banks were called ANxx). Data Words --------- Data types: B(bit), I, F, D(double), H(hollerith 4 char) Fixed length Database Header. See titles_dbhdr.html Word Type Description ---- ---- ----------- 1 I Max number of bad channels The remainder of the bank consists list of variable length entries. Each entry has the format:- i+1 I Logical channel number or -9999 to signal last entry. +2 I Number of flagged types =n. +3 I First flagged type. ... +2+n I Last flagged type. Where flagged type is an integer corresponding to the type of flagging mechanism in question. The list of bits can be found in anxx_data_com.inc A tube might be bad for tac, qhl, but still be of some use for occupancy studies.
