A formula is given in this section for the number of data elements in the binary tables.
Table A.1. Table size variables
| variable | description (number of) | range (EVLA) | notes |
|---|---|---|---|
| B | basebands | 1-8 | constant |
| N | antennas | 1-32 | constant |
| L | baselines | 1-496 | constant for any table: crossData table includes only off-diagonal baselines, autoData and zeroLag tables include only on-diagonal baselines, all other tables include all baselines |
| W | spectral windows | 1-16 | can vary by baseband |
| F | phase bins | 1-65,536 | can vary by baseband and spectral window |
| A | APC bins | 1-2 | constant |
| C | spectral channels | 1-262,144 | can vary by baseband and spectral window |
| P | polarization products | 1,2,4 | can vary by baseband and spectral window |
Variables that are not noted in Table A.1, “Table size variables” as being constant may appear with
subscripts in the formula. Each of the variables from the
table appears in the formula with a “prime”
symbol to indicate that, if the corresponding axis has been
omitted from the binary table in the data stream, the variable
has a value of one.
