In total, the database contains the wavelengths of 91,000 lines of about 900 spectra in the range from 0.1 nm to 2,000 pm. Also, for about one-half of the lines, atomic transition probabilities are available with estimated uncertainties, which are listed by code letters (A < 3%, B < 10%, C < 25%, D < 50%). 

As cited in Chap. 6, basic instrumentation costs range from 3 to 20 per cent of installed equipment costs, depending oh the completeness of automatic control. Detailed instrumentation costs are required for final cost estimates within 10 per cent. Instrumentation as listed by code numbers from the instrumentation flow sheets is set up as separate instrument items on specification sheets and sent to suppliers. Firm quotations are received after mutual agreement on the correct type and application is reached among the purchasing and manufacturing personnel. Table 9-18 lists typical instrument and auxiliary costs which can be used for estimating purposes in lieu of actual quotations.
