... In the very first iteration, the user is required to input the true coordinates of at least two sources interactively. For this Ds9 is launched showing an image that has been accumulated from the input event list with all found sources marked through excluded circles . For each source that is to be used as a reference source the user needs to: . ... There is an alternative reference source input method available that is activated with the withrefsrclist parameter. ...

... This discussion begins by noting that stellar photometry is often done quite effectively on unrestored images. Even when restoration is necessary, one must be wary of sophisticated methods, many of which distort photometric values. ...

EXPLANATION OF DANA'S FIBER TESTS ON THE 12M TELESCOPE.. ... But we know full well that this is not directly possible- the delay in the optical fiber carrying this signal will change both with temperature and to some degree with fiber bending as the telescope tracks objects or moves from one object to another. ... So we would like to identify at least one pair of single mode fibers in our bundle, whose delay changes due to antenna tracking etc are pretty well matched. ...
