"<emphasis role=\"bold\">Iterative</emphasis>: In the Iterative algorithm, "
"Ekos operates iteratively by moving in discrete steps, decided initially by "
"the user-configurable step size and later by the slope of the V-Curve, to "
"get closer to the optimal focus position where it then changes gears and "
"performs smaller, finer moves to reach the optimal focus. The focus process "
"stops when the measured HFR is within the configurable tolerance of the "
"minimum recorded HFR in the process. In other words, whenever the process "
"starts searching for a solution within a narrowly limited range, it checks "
"if the current HFR is within % difference compared to the minimum HFR "
"recorded, and if this condition is met then the Autofocus process is "
"considered successful. The default value is set to 1% and is sufficient for "
"most situations. The Step options specify the number of initial ticks the "
"focuser has to move. If the image is severely out of focus, we set the step "
"size high (i.e. greater than 250). On the other hand, if the focus is close "
"to optimal focus, we set the step size to a more reasonable range (less than "
"50). It takes trial and error to find the best starting tick, but Ekos only "
"uses that for the first focus motion, as all subsequent motions depend on "
"the V-Curve slope calculations. Key features include:"
msgstr ""
"<emphasis role=\"bold\">Iteratiu</emphasis>: En l'algorisme iteratiu, Ekos "
"funciona de manera iterativa movent-se en passos discrets, inicialment "
"decidit per la mida del pas configurable per l'usuari i més tard per la "
"inclinació de la corba V, per a acostar-se a la posició d'enfocament òptima, "
"on canviarà de comportament i començarà a realitzar canvis més ajustats fins "
"a aconseguir l'enfocament òptim. El procés d'enfocament es pararà quan l'HFR "
"es mesure dins de la tolerància configurable de l'HFR mínim enregistrat "
"durant el procés. En altres paraules, cada vegada que el procés comence a "
"buscar una solució dins d'un interval limitat, comprovarà si l'HFR actual es "
"troba dins del tant per cent de diferència en comparació amb l'HFR mínim "
"enregistrat, i si es complix esta condició, el procés d'enfocament automàtic "
"es considerarà vàlid. El valor predeterminat s'establix en un 1% i és "
"suficient per a la majoria de situacions. L'opció Pas especifica el nombre "
"de marques inicials que l'enfocador s'haurà de moure. Si la imatge està "
"greument fora d'enfocament, establirem la mida del pas alt (açò és, superior "
"a 250). D'altra banda, si l'enfocament s'aproxima a l'enfocament òptim, "
"establirem la mida del pas en un interval més raonable (inferior a 50). Es "
"requerix prova i error per a trobar la millor marca inicial, però Ekos només "
"ho farà servir per al primer moviment d'enfocament, ja que tots els "
"moviments posteriors dependran del càlcul de la inclinació de la corba V. "

"The Levenberg-Marquardt algorithm is a non-linear least-squares solver and "
"thus suitable for many different equations. The basic idea is to adjust the "
"equation y = f(x,P) so that the computed y values are as close as possible "
"to the y values of the datapoints provided, so that the resultant curve fits "
"the data as best as it can. P is a set of parameters that are varied by the "
"solver in order to find the best fit. The solver measures how far away the "
"curve is at each data point, squares the result and adds them all up. This "
"is the number to be minimized, let's call it S. The solver is supplied with "
"an initial guess for the parameters, P. It calculates S, makes an adjustment "
"to P and calculates a new S1. Provided S1 &lt; S then we are moving in the "
