AO Project A1946 Planning Documents:

Our precursor program was allotted telescope time in Aug-Sep 2004 under program A1946. Since not all of that time was successful and many changes have been taking place, we hope to have more time in Jan-Feb 2005.

IDL Software Development:

The Cornell group has been working with Arecibo staff to develop IDL routines for the reduction of mapping data in anticipation of the August A1946 observing run. Routines are being tested on single pixel mapping data obtained in 2003 using the interim correlator under projects A1705 and A1763. The approach is based on Phil Perillat's extensive routines for mapping data using either the Interim Correlator (IC) or the WAPPs.
