Please note: Dark Skies was created in Kontakt 3.5 so earlier versions of Kontakt will not be able to open the files. Zero-G offer a free download of the Kontakt2 instruments to any Dark Skies purchaser who needs the .nki files to work in Kontakt 2 or 3. Email information@zero-g.co.uk and Zero-G will send the files. The included Kontakt Files will not work in the free Kontakt Player. Users are still able to use the other included sample formats, even if they do not own Kontakt.
The air mass zero (AM0), or extraterrestrial spectrum used to generate the terrestrial reference spectra was developed by Gueymard and is a synthesis of several air mass zero data sets. (See Gueymard 2004 for an historical perspective.) Note the spectrum used in conjunction with SMARTS to produce the reference spectra is not the air mass zero spectrum in ASTM E-490-99, as there are slight differences in bandpass and spectral resolution for the two spectra.

myDataBank allows you to derive your own Custom Indicators from existing series. Click on Custom Indicators. Choose input indicators by clicking on the desired series in the panel and use the calculator functions to construct your custom indicator formula. For example, for a series that shows the percentage of female population, double-click on the series Population, Female. Then create a formula by clicking*100/ from the key pad. Then double click on the series Population, Total. After the formula is complete, you can verify its syntax by clicking the "> Validate icon. Give a name to your custom indicator and click on Add. Similarly you can create custom indicators such as GDP per Capita as GDP/Population, and annual growth rates for population as AGR(Population, Total), etc. To have "not available" values in the database treated as zero within your formula, use the NA function.
Employees must be counted by veteran category as either new hires or current employees for each job category listed in the VETS-4212 report. If the company does not employ covered veterans during a reporting period, it may enter zeros or leave the spaces blank. Blank spaces will be considered zeros.
They flew one more Martian gravity parabola followed by two lunar gravity parabolas. The gravitational field strength on the surface of the Moon is 1.62 N/kg. This means the plane had to fly with a downward acceleration of about 8.2 m/s2. The reduced gravity parabolas help passengers physically adjust before going zero-g. The 15 parabola flights only have one Martian and lunar parabola. I alternated between taking a video of the Kundt's tube (more on this later) and hopping around. Some passengers did 1-arm pushups and other feats of strength. The lunar gravity was especially fun, and I envy the future tourists who will travel to the Moon.
What is interesting about that? The fundamental frequency measured at PASCO was 186 Hz. This gave a speed of sound of 342 m/s. Why the difference? I first thought it was the lower cabin pressure. Planes typically are pressurized to the equivalent of about 8000 ft. My college chemistry teacher would have been disappointed by my hypothesis because I am sure I learned that the speed of sound does not vary with pressure. It seems like it should because at zero pressure there is no speed of sound. Shouldn't it gradually get slower as the pressure is reduced? The answer is that the speed of sound gets smaller as pressure is reduced, but it increases as density is reduced. These two factors cancel out. The difference was due to a difference in temperature. We can estimate the temperature from the speed of sound. The equation below solves for the speed of sound in air at a given temperature.
It was fascinating to observe this phenomenon firsthand. The close-up shots of the bottle are from the GoPro camera I Velcroed to my chest. The GoPro worked great when I tested it in my hotel room, but I was disappointed by the quality of my footage after the flight. In the hotel room, gravity pulled on the camera keeping it stable. In free fall, it tilted up and down from the slightest jostling. Most of the GoPro footage proved unwatchable. I will mount it to the cabin wall in future flights, so I can film experiments hands-free. Here's an unrelated (and very cool) video of participants trying to catch water in zero-g.
When the graph is at or near zero, the plane is in Martian gravity, lunar gravity, or free fall. The free fall parabolas occur after the first 3. I measured the duration of a few and found them to be about 20 s each. The screenshot below shows a free fall with a steady reading. I used SPARKvue's Delta Tool to measure a duration of 19.6 s.
PASCO's SPARKvue software has an analysis tool that integrates the acceleration data to find the vertical velocity of the plane. I normalized the values by subtracting 9.81 m/s2 from the data. There was a small drift that had to be subtracted too. I took one section of a parabola and set the initial vertical velocity to zero and produced the graph below. If you want to see the details of these calculations, they are in the SPARKvue file I linked to above. The graph shows the vertical velocity graph below the acceleration graph. Vertical velocity in m/s is on the vertical axis and time in seconds on the horizontal axis.
This is counter-intuitive for many people, including Miles O'Brien in the CNN video. It is not surprising because the word "fall" is almost always used to describe something that is heading toward the ground. Eventually, the plane's vertical speed reaches zero, and it starts speeding up on the way down. The 212 m/s change in velocity during the 20.8 s free fall period shown on the graph checks out. Accelerating at 9.81 m/s2 for 20.8 s would cause a 204 m/s change in vertical velocity. If my analysis is correct, then the plane reaches a maximum downward speed of 147 m/s (327 mph!) after the first parabola on the graph. We were falling with style. I like to imagine the shock of students coming up with this value in class as they realize their teacher was hurtling toward the ground at 327 mph. It shocked me when I first calculated it.
Marsh gave us some specific advice for avoiding motion sickness: lie on your back between free falls and stare at a spot on the ceiling, take it easy for the first 5-6 zero-g parabolas, and avoid doing spins and flips unless you feel exceptionally good. If you must do a spin or flip, wait until the last parabola. Overall, I felt pretty good except during the 1 g turnarounds. The only time free fall bothered me was when I was focusing on adjusting the signal generator frequency and keeping the Kundt's tube working. I chose to not do any spins or flips until the end. When they announced, "last parabola" I was feeling okay and decided to do a spin, moving my arms in and out like a figure skater. I didn't get much of a speed increase, but I was happy to do a spin and hoped the cameraman got a good shot. You can see below that he did!
Specify converters for columns. This is useful for numerical text data that hasleading zeros. By default columns that are numerical are cast to numerictypes and the leading zeros are lost. To avoid this, we can convert thesecolumns to strings.
