... HST . Example 12 . ... 1] Align and combine the F160W frames. When 'expand_refcat=True' and 'enforce_user_order=False', TweakReg will select the image with the largest overlap and work out from there, expanding the reference catalog as it goes. ... Because no reference image was explicitly defined, TweakReg selects the two images in visit 02 as having the largest overlap and aligns them by matching sources. ... 3] Now we align the F110W frames to the drizzled F160W reference image. ...

For this example of NPOI data reduction and analysis we use observations of Mizar from 1997. ... They include reading the raw data and computing visibilities (done by a standalone C program called CONSTRICTOR), editing the 1s incoherent averages and averaging these data for every scan. The latter steps are done with OYSTER, but for this lab it is not useful to have these steps performed by the participants. ... Background data loaded. ... Finished reading catalogs. ...

The aim of this assignment is to teach you how to carry out a very common programming task: reading in a bunch of data from a text file, doing something with it then writing the results out again. ... The goal of the assignment is to write a computer program which will select this sample for you. You will pick the micro-quasars to observe from a rather large catalogue, which can be found here: The catalogue is an ASCII (text) file - you can inspect it with a normal text editor. ...

... The Radon transform (also known as the Hough transform) is formulated as a family of line integrals through a two-dimensional function. ... The Radon transform provides us with a simple means of computing the FF plane of the autochirplet transform, by using the Wigner distribution, and arriving at a transform space that tells us basically the same information as the chirplet FF-plane, except that we benefit from the greater resolution of the Wigner distribution. ...
