HXT has a large effective area. Accordingly, its four energy channels can be used for ordinary spectrophotometry via direct summation of the rates from the 64 independent detectors, independently of any application of these data to imaging. The data are well-calibrated and are normally free of any effects of pulse pile-up, owing to the small effective areas of the individual detectors. The four channels can be used to fit power-law or thermal spectra. The presence of spatial structure in the image affects the precision of the total-count photometry, but because there are 64 detectors, this effect is probably small.
