4.2.3 Processed data

• Data_Red: this 2D array contains the reduced data after each processing step. It is first initialised with a copy of the raw data.
• Data_Bac: after every processing step, the data previously contained in Data_Red are copied to this backup array, to enable a quick 'undo' procedure.
• Data_Flag: used to flag inidividual data points.
• Data_Noi: rms noise associated with individual data points.
• Channel_Flag: used to flag channels.
• FFCF_CN: correlated noise.
• FFCF_Gain: computed flat field.
• Channel_rms: rms noise, per channel.
• Channel_mean: mean value, per channel.
• Results: depending on the type of observation, this can contain one or several numbers. It can also contain the results of several scans of the same type (e.g. when one wants to combine the results of several successive pointings).
• Weights: to be applied to the results (see previous item).
• Command_History: this is used to store the commands that are typed into BoA, in string format. This can then be saved into a script file, that can later be edited and imported again into BoA.
