Yes. A "parsec" is the abbreviation for a parallax-second of arc, a measure of distance.
I have no idea what a "secpar" is, but it might be the abbreviation for some sort of government official, "Secretary of Parking" perhaps.
parallax second When we observe a star from opposite ends of the Earth's orbit, if there is a parallax difference of 1 arc second, that star is 1 parsec away.
About 206,000 given that 1 parsec is 3.06 x 1013 km and 1 AU is 149.6 x 106 km __________________ 1 Astronomical Unit (AU) is the average distance from the Sun to the Earth, about 150 million kilometers or 93 million miles (approximately). We use AU when we talk about distances between objects WITHIN the solar system. One "parsec", or "parallax-second of arc", is the distance that an object would be (from Earth) if we measure a one second of arc difference in the relative direction of a "nearby" object, measured from one side of the Earth's orbit to the other. That gives us a baseline distance of 2 AU, about 300 million km or 186 million miles. You can calculate the distance of one parsec using trigonometry; the base of the triangle is 2AU, and the opposite angle is 1 second of arc (1/3600th of a degree). Roughly, one parsec is about 3.26 light years. We use parsecs to measure distance between stars, or between objects in the galaxy.
1 parsec is 3.26 light-years. 100 parsecs is 326 light-years. D(ly) = D(pc) x 3.26
1 Parsec = 3.26163626 light years
. . they are a convenient unit. Another convenient unit is the parsec.

1 parsec = 19,173,510,995,000 miles.
1 Parsec = 3.08568025 × 1013 kilometers.
1 Parsec = 3.08568025 × 1016 meters.
1 parsec is 3.26 light-years. 100 parsecs is 326 light-years. D(ly) = D(pc) x 3.26
Me, I'm torn between the Smoot and the Parsec
1 Parsec = 3.26163626 light years
1 parsec is 3.09 x 1016 meters.
Parsec - video game - was created in 1982.
