irable to choose <span class="nowrap">P<sub>a</sub></span> to be as close to the measured value as possible. If <span class="nowrap">P<sub>a</sub></span> = 27.5546, n would be <span class="nowrap">3652412.6543/27.5546</span> = 1332551.83, which is not an integer. We can take the nearest integer and set <span class="nowrap">P<sub>a</sub></span> = <span class="nowrap">3652412.6543/132552</span> = 27.55456465613495 days, which is only 3 seconds less than the measurement value. We can safely assume that the mea
