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.
That takes us up to the next level. Great pogntis.
How in the world is itï»¿ possible she had a boob job with a full time cheer coaching job which she has to stay fit and healthy for and aï»¿ son? When could she have any time to go through the operation and recover??
kÃ¶szÃ¶nÃ¶m a jÃ³kÃvÃ¡nsÃ¡gokat.@Szeretet: nem tudom, hogy miÃ³ta olvasol bennÃ¼nket, de nem gondoljuk, hogy a blog akkora szomorÃºsÃ¡got sugÃ¡rozna. (LÃ¡sd a papÃrcsÃ¶ves bejegyzÃ©st, a lejtÅ‘n mÃ¡szÃ¡st Ã©s a tÃ¶bbit, ahol az erÅ‘feszÃtÃ©seink hatÃ¡sÃ¡ra pici, de stabil eredmÃ©nyek szÃ¼lettek). A taposÃ³malom pedig kÃ¶nnyen kikÃ©szÃtene bÃ¡rkit, aki reggeltÅ‘l estig naponta Ã³rÃ¡kat fejleszti a babÃ¡jÃ¡t – erre biztos nem jÃ³ megoldÃ¡s a picit intÃ©zetbe adni. Egy pÃ¡r napra a nagyira vagy mÃ¡s olyan ismerÅ‘sre bÃzni, aki megbÃzhatÃ³an ellÃ¡tja Ã©s tornÃ¡zik is vele – az termÃ©szetesen megoldÃ¡s lehet…
