... The concerns here are similar to those for observing bright targets; saturation and blooming of the bright companion PSF must not impact the faint target. Also, one may need to consider subtracting the PSF of the bright object, and effects which limit the accuracy of that subtraction. If the bright companion will saturate and bloom, it will be necessary to rotate the CCD so that blooming along the CCD columns does not obliterate the faint target. ...

. This diagram maps the data gathered from 1994-2013 on small asteroids impacting Earth's atmosphere to create bright meteors, technically called "bolides" and commonly referred to as "fireballs." Sizes of red dots (daytime impacts) and blue dots (nighttime impacts) are proportional to the optical radiated energy of impacts measured in billions of Joules (GJ) of energy, and show the location of impacts from objects about 3 feet (1 meter) to almost 60 feet (20 meters) in size.

... The routine processing of STIS data in the calibration ``pipeline" requires an interrelated set of software tasks and databases developed and maintained by many groups at STScI. We present the systems-level design of this calibration pipeline from the perspective of the STIS instrument group at STScI. We describe the multiple interfaces to the pipeline processes that the STIS group works across in an effort to provide for the routine calibration of STIS data. ... For example, the STIS group: . ...
