Note, however, that these are just the products The used total images areĪvailable upon request. In the final combined image, provided here. Process of combining individual subimages (all in MIRphot), instead of Results table, because many flux measurements were performed during the Not necessarily exactly equal to the values provided in the photometry In particular for the instruments, VISIR and COMICS, they are Values given in the FITS headers should be regarded as approximate Other flux measurement methods are applied to the images. Therefore, correction factors have to be applied in case Using the median conversion factor for the used instrument/filter The FITS images are flux calibrated (unit is mJy) using the Gaussian 2Dįits to the corresponding STD observation (where available, otherwise In addition, the imprecision of the assignment itself is ~1px ~
