Abstract

The intention here is to summarize aspects of observational astronomy relevant to light curve acquisition and modeling. Thus, we discuss passband1 profiles of observational data because some codes no longer consider the observations to be monochromatic fluxes. Passbands are finite wavelength-width stretches of the electromagnetic spectrum. Sources of errors in the observational data are discussed because light curve analysis codes can have weighting which is light-level dependent. Such errors depend to a large extent on observational techniques, so these too need to be described. The incorporation of Doppler profile analysis techniques in light curve codes requires high-resolution spectrophotometric data with excellent signal-to-noise ratios to extract profile information. The same can be said for magnetometry. Polarization data require another dimension of information in the form of a series of position angle measurements.
