===== Editing Pitot Wing Data - CapeEx19 =====
==== Reason for editing ====
  - During ongoing aircraft field research in Florida in 2019, the aircraft's wing pitot sensor was found to be providing erroneous readings.
  - During the creation of the physical file, the process_all script consolidates the CIP pitot pressure into the wing pitot pressure spot; consequently, the anomalous data is utilized to generate the .basic.raw file.
  - The CIP pitot pressure is about 10 mb lower than the nose pitot pressure.

=== How to remove the corrupted data ===

  - Connect to vpn.ndus.edu through Global Protect
  - Open and log into the Littlestorm server through PuTTY.
  - After logging in, type in the command: **cd /nas/und/Florida/2019/Aircraft/CitationII_N555DS/FlightData**
  - After going to the FlightData directory, look inside it for a subdirectory named after the specific date of flight you want to see. For instance, I chose the 20190803_142455 flight data to make changes.
  - After selecting the directory of interest, type: **cd PostProcessing**
  - Navigate to the **.physical.raw.gz** file.
=== Editing the file and data inside it: ===
 
   - First, if the file is compressed, meaning it is in .gz format, then decompress it using the command: **gunzip 19_08_03_14_24_55.physical.raw**
   - Once the file is in decompressed form, type: **aplot 19_08_03_14_24_55.physical.raw**
   - This command will open ADPAA Aplot.
   - Select **'Pitot_Wing'** and then **XY Plot**
   - To look at the time interval of this flight, click the Tools tab located at the top of the bar.
   - Under the Tools section, click **"Statistics"**. A side window will be opened, which displays the X-span (time interval).
   - Notice the Minimum and Maximum time.
   - Under the File tab, go to the "Add Edit" option.
   - Type the **minimum time** as Start Time and the **maximum time** as End Time.
   - Type in the editor name
   - Select the parameter as Pitot_Wing
   - Then, please specify the reason for making the edit. For example, I might indicate "Not connected, negative values."
   - Click **"Store Edit info"**. This will create a .physical.edits file in the directory you are in. 
   - Proceed to the File tab and select **"Apply edits"**. This action will generate a .physical.cleans file within the directory. 
   - The physical. cleans file will exclude data from the Pitot_wing sensor.
