A TOA5 header contains the metadata described below. Other data formats contain similar information unless a non-header format option is selected in the TableFile() instruction in the CR1000 CRBasic program. Line 1 - Data Origins Includes the following metadata series: file type, station name, CR1000 model name, CR1000 serial number, OS version, CRBasic program name, program signature, data‐table name. Line 2 - Data-Field Names Lists the name of individual data fields. If the field is an element of an array, the name will be followed by a comma‐separated list of subscripts within parentheses that identifies the array index. For example, a variable named "values" that is declared as a two‐by‐two array, i.e., Public Values(2,2) will be represented by four field names: "values(1,1)", "values(1,2)", "values(2,1)", and "values(2,2)". Scalar (non‐array) variables will not have subscripts. Line 3 - Data Units Includes the units associated with each field in the record. If no units are programmed in the CR1000 CRBasic program, an empty string is entered for that field. Line 4 - Data-Processing Descriptors Entries describe what type of processing was performed in the CR1000 to produce corresponding data, e.g., Smp indicates samples, Min indicates minima. If there is no recognized processing for a field, it is assigned an empty string. There will be one descriptor for each field name given on Header Line 2. 338
