How many stars within 5 parsecs? Also, the Tycho catalog guide, vol. 1 gives the median astrometric precision of all stars as 25 mas or 7 mas for $V_T$ < 9 mag. |

How many stars within 5 parsecs? Explain what happens if I discard negative parallaxes. |

How many stars within 5 parsecs? That's weird, but OK. So, I should just outright discard negative parallaxes? (I took the absolute value.) What about the "missing" stars in the Hipparcos catalog? |

How many stars within 5 parsecs? I don't know, but to double-triple-super-mega-check, I've taken those records apart by hand. Negative parallaxes. |

How many stars within 5 parsecs? See cdsarc.u-strasbg.fr/viz-bin/Cat?I/239#sRM2.13 And why couldn't those be parallax values? Also, I initially did use the delimited field approach, but I got the same results. I switched to fixed offsets because it ran faster. |

Amplitude at distance from source So, er, $A^2 \sim \frac{1}{x^2}$ and therefore $A \sim \frac{1}{x}$? |
