Estimate, in pc, the distance to Eta Aquilae A(i) using the parallax angle in the table.

To estimate the distance to Eta Aquilae A(i) using the parallax angle, we will follow the steps below.

1. Break Down the Problem

We know that distance (d) in parsecs (pc) can be calculated using the formula: $d = \frac{1}{p}$ where $p$ is the parallax angle measured in arcseconds.

2. Relevant Concepts

The formula for calculating distance based on parallax is derived from the definition of a parsec. One parsec is the distance at which one astronomical unit subtends an angle of one arcsecond.

3. Analysis and Detail

Let's assume the parallax angle $p$ of Eta Aquilae A(i) is provided in the table you mentioned (although it's not provided here). You will need to substitute the value of $p$ in arcseconds into the formula.

For example, if the parallax $p$ is given as $0.1$ arcseconds: $d = \frac{1}{0.1} = 10 \text{ pc}$

If the value of $p$ is different, adjust the calculation accordingly.

4. Verify and Summarize

Ensure that the parallax angle is in arcseconds, and check calculations for any rounding errors.

Final Answer

If $p = 0.1$ arcseconds, then the distance to Eta Aquilae A(i) is: $d = 10 \text{ pc}$ Please replace $0.1$ with the actual parallax angle to compute the correct distance.
