Add the remaining astrometric orbital elements to the fit parameters, and vary the secondary mass only. ... In this case, you may add also the primary mass to the fit parameters as the system is now constrained just like a double-lined spectroscopic binary. ...

... Parameters of the Moon-perturbed orbit . ... From orbits consistent with this limitation and with the date of the launch October 1, 2000 as an example, an orbit was selected with apogee directed to the North Galactic pole at the begining and rotation of orbit plane was maximized. The initial state vector is given in the inertial coordinate system in epoch J2000.0. ... The orbit has initial perigee radius Rp=7000.0 km, initial apogee radius Ra=343000.0 km and initial period T=8.453 days. ...

... First, we computed the mean errors of orbit parameters on the assumption of the linear connection of them with observation errors and then we compared obtained estimates with those resulting from the assumption of the nonlinearity of this connection. Secondly, we correlate orbital parameters and their errors obtained by the method of the least modulus with those obtained by the least-squares method. ...

... We demonstrate through numerical simulations that model parameters estimated with our technique are essentially bias-free, even when the average number of counts per bin is 1. ... The IW technique avoids such biases by estimating through successive iterations, where for each iteration, j, , and the best-fit parameters are determined by minimization of . ... In our sample, we find that the minimum values and best-fit parameters converge after about 6 iterations. ...

... Posts tagged ?parameter estimation? ... Leccardi & Molendi (2007) have a paper in A&A ( astro-ph/0705.4199 ) discussing the biases in parameter estimation when spectral fitting is confronted with low counts data. Not surprisingly, they find that the bias is higher for lower counts, for standard chisq compared to C-stat, for grouped data compared to ungrouped. ...

External influences on spin parameters for INTERBALL - AP . ... The main interest is that almost all kind of external influences to parameters of motion (eclipse, normalization, ROS) are presented in the one time interval.

... The binary nature was remarked by Deutsch, approximate orbital elements were at first derived in Potsdam. Recently, 53 Cam was directly resolved by speckle-interferometric measurements of McAlister et al. and Balega. Combining with the spectroscopic elements the determination of the absolute values of the system parameters should be possible. In the present paper a revision of the spectroscopic orbital elements and a comparison of spectroscopic and speckle data have been carried out. ...
