9.6.5 Example 5: Coronagraphic imaging of the Beta-Pictoris Disk


In the final example we shall consider the case where we are trying to determine the S/N achieved on the Beta Pictoris disk, assuming a disk surface brightness of R magnitude of 16 arcseconds2 at a distance of 6 arcseconds from the central star with a V magnitude of 3.9, for an exposure time of 1000 seconds with an F435W filter. Assume that the star and disk have an A5 V-type spectrum. Using the ACS Exposure Time Calculator and considering the case for the 3.0arcseconds occulting mask:
