AstroFest 2007 (Texas)

I’ll be at AstroFest hanging out, meeting students, and giving a talk on standard star calibrations. If you’re an an SAO alum, consider coming 🙂

Here’s the info on the talk I’ll be giving:

Standard Stars, Standard Colors, and the art of not being unique
Every set of optics has its own unique set of issues. Some are a little insensitive in the blue, some have something against red. Some filters let through a little more square of a band pass of light, and others let through more sloped a spectral energy distribution. These system to system irregularities mean that a particular star’s instrumental B-V on one scope is not the same as its instrumental B-V on a different telescope. Complicating this are atmospheric differences that cause different amounts of different wavelengths to be transmitted in different locations. For astronomical results between different scopes to be compared, astronomers must be able to transform instrumental magnitudes to a standard system. This is possible using all sky photometry on a photometric night.
In this session we will discuss how to obtain the observations necessary to transform observations to a standard system, as well as how to calculate the the needed transformation coefficients. The session will be divided into two parts, a lecture component and a practical session that will work through provided data.


  1. That takes us up to the next level. Great pogntis.

  2. How in the world is it possible she had a boob job with a full time cheer coaching job which she has to stay fit and healthy for and a son? When could she have any time to go through the operation and recover??

  3. köszönöm a jókívánságokat.@Szeretet: nem tudom, hogy mióta olvasol bennünket, de nem gondoljuk, hogy a blog akkora szomorúságot sugározna. (Lásd a papírcsöves bejegyzést, a lejtÅ‘n mászást és a többit, ahol az erÅ‘feszítéseink hatására pici, de stabil eredmények születtek). A taposómalom pedig könnyen kikészítene bárkit, aki reggeltÅ‘l estig naponta órákat fejleszti a babáját – erre biztos nem jó megoldás a picit intézetbe adni. Egy pár napra a nagyira vagy más olyan ismerÅ‘sre bízni, aki megbízhatóan ellátja és tornázik is vele – az természetesen megoldás lehet…
