In instrpars, the parameters of greatest concern to you will be "setfocus", "temperature", "basefocus", and "reftemp". By setting "setfocus" to "auto" (RECOMMENDED), you allow the telescope to update its focus for changes in temperature (using the coefficient in "tfrcoefs", where "1 -135.0" means a change of -135 microns of focus for a 1 degree change in temperature). This procedure is described in detail below, under the focus procedures. You should also normally leave "setfilters" to "yes", so that the Arcon will ask you for the filter whenever you take an exposure. The ONLY reason you would want to set it to "no" (in which case Arcon uses whatever filter is in "filter1"), is if your program uses only one filter.
