 1d awarded Notable Question Apr 16 accepted Error propagation estimation Apr 15 comment Error propagation estimation why did you have obtained $3 \sigma_A/A?$ what's the difference with this formula? en.wikipedia.org/wiki/Propagation_of_uncertainty#Simplification many thanks Apr 15 comment Error propagation estimation Could you explain me how you have obtained the second results? thanks Apr 15 comment Error propagation estimation @Numrok Question edited. Please, let me know if you need other details. Many thanks Apr 15 revised Error propagation estimation added 378 characters in body Apr 15 comment Error propagation estimation @Numrok yes, I know them. For example, $log M=(0.755 \pm 0.059)*log B+(0.416\pm 0.024)$. The value of B is given by a software and its error is 0.0002. Using the fomulas, I get M and N. It is assumed that the error on M and N is 15%. I'd like to know how the error on B affect the value of A.

Could you give me some formula or references to calculate bolometric flux? I have found this paper articles.adsabs.harvard.edu/cgi-bin/… but I haven't understood in which way I can use it... Mar 11 comment Light curve analysis: how to estimate temperatures of Binary star system A lot of thanks, I'm not an astrophysics student, so I have some doubts... If I want to calculate the flux at the minima, is it correct the formula $F_v=10^(-0.4 (V_{mag}-V_{min}))$ where $V_{mag}$ is the apparent magnitude at the minima and $V_{min}$ is the minimum value of the magnitude? And then How can I obtain the bolometric flux? A lot of thanks for your help Mar 11 revised Light curve analysis: how to estimate temperatures of Binary star system added 14 characters in body Mar 11 comment Light curve analysis: how to estimate temperatures of Binary star system @RobJeffries you're right. In fact I also have an estimation for distance. Can you give some hints about how to proceed?

Feb 8 comment Diagonal of a thin rectangular foil, inertial principal axis? Why, for example, the second term in the first row is 0?
