This spectrum was extracted from the ECAS data set and reformatted for ease of access. For additional documentation of the ECAS system, such as filter bandpasses, standard stars, and a description of the instrument, see the ECAS data set in the main PDS archive. Standard deviations are given to one thousandth of a magnitude. The standard deviation for the V magnitude reflects, in some cases, the variation caused by the rotational lightcurve, rather than the scatter in the photometry. The Universal Time of the observation represents the middle of the observation. Each cycle through the filter set represents 72 seconds of integration time; with deadtime taken into consideration, this information can be used to estimate the total time spanned by the observation.
