Arecibo Observatory Technical Memo AOTM 2000­01 THE LBW FEED: THE MUELLER MATRIX IN 1999 AND 2000 Carl Heiles ABSTRACT We present measurements of the Mueller matrix and associated quantities at two epochs for 1420.4 MHz (February­March 1999 and March 2000) and one for 1665.3 MHz (March 2000). ... SUMMARY AND RESULTS In AOTM 99­01, we presented the theory and practice of deriving the Mueller matrix for the LBW system. ... Delta\Phi = \Phi XY;SKY \Gamma \Phi XY;CAL as defined in x2.1 of AOTM 99­01. ...

... Meta Index / Home Page . omthlcplot reads the OM tracking history FITS file and then plots the intensity of each star as a time series. omthlcplot is flexible enough to present each time series on a separate page, on several pages or all the time series may be presented on a single page, specified using the parameter nplots . ... The input FITS files, such as those that have ben produced by omthconv , can contain between 1 and 99 rates columns, with equi-spaced time bins. ...

Stellar Clusters are very useful laboratories for empirically studying stellar evolution. ... All cluster stars are at the same distance . All cluster stars have the same physical age . ... CM diagram Young Cluster In this case we see the Main Sequence fully represented. The blue dots represent massive stars with short main sequence lifetimes. ... Thus, identifying the most massive star which is still on the main sequence is an effective means of determining the age of a stellar cluster. ...
