From Jonathan.Davies@astro.cf.ac.uk Mon Mar 22 09:55:41 2004 Date: Fri, 19 Mar 2004 09:58:30 +0000 (GMT) From: Jonathan Davies To: Judith Irwin Cc: Jonathan Davies , Suzanne.Linder@astro.cf.ac.uk, hoffmang@lafayette.edu Subject: Re: Beam map for the L-wide receiver (fwd) This is the message I had about the beam map. If I can help in any way please let me know. Jon Hi Jon, Phil has now made beam maps for the L-band wide receiver. I attach his email here from which you will know where to find it. The average/median/min maps are scaled so that the maximum pixel value is 1 - you can also see a contour plot (using the old AIPS) at www.naic.edu/~tghosh/FOT/lbwavgbeam.ps - please let me/phil know if you have any more questions. All the best, Tapasi ----------------------------------- Phil's notes on this --------------- lbw beam maps /share/megs/phil/bmaps/lbw dobmap.pro,doit.pro - example of code to create beammaps. subdir src za size freq 040130 B1843+098 14Rising +/-5 FWHm 1405 B1843+098 16Setting +/-5 FWHm 1405 B1607+268 10Rising +/-5 FWHm 1405 B1607+268 16settin +/-5 FWHm 1405 lbwBmAvg4 average above 4 lbwBmMin4 min above 4 lbwBmMed4 median above 4 Notes: grid 1amin, gauss smooth .1*fwhm. +/ 5 fwhm sampling.
