How to fill out the Sight Reduction Form online
Filling out the Sight Reduction Form online is a systematic process that helps users calculate astronomical positions for navigation. This guide provides clear, step-by-step instructions to ensure accurate completion of the form, catering to users of all experience levels.
Follow the steps to successfully complete the Sight Reduction Form.
- Click ‘Get Form’ button to access the Sight Reduction Form and open it for editing.
- Begin by entering the date and Universal Time (UT) of your observation. These fields are crucial as they affect subsequent calculations.
- In the ‘Estimated Latitude & Longitude’ section, provide your best estimates. Ensure the latitude is in degrees and minutes, while longitude should reflect negative values for west longitudes.
- Next, move to the ‘Calculate Altitude & Azimuth’ section. Here, derive the Declination (Dec) from the almanac which you will use in further calculations.
- For the GHA calculation, add the GHA Aries to the SHA value you found. Ensure to keep values between 0° and 360° by removing multiples of 360°.
- Proceed to calculate the Local Hour Angle (LHA) by adding the calculated GHA to your assumed longitude.
- In the reduction table, record your values for latitude and LHA. Calculate A degree based upon these recorded values for further reductions.
- Continue through the auxiliary tables where you will calculate corrections based on your obtained values. Record the correlations to adjust your altitude calculations accurately.
- After filling all calculations and corrections, finalize your Calculated Altitude (Hc) and complete the azimuth calculations.
- Finally, review all entries for accuracy. Once confirmed, you can save changes, download, print, or share the completed Sight Reduction Form.
