PERFORMANCE-CHARACTERISTICS OF THE ADVANCED STOKES POLARIMETER

Recently Zirin (1995) published a response to our paper of last year ( Lites, Martinet Pillet, and Skumanich, 1994), in which we quantified s ome limitations of vector magnetometry by the use of a generic filter magnetograph. Zirin's Letter makes specific reference to the Advanced Stokes Polarimeter (ASP), and in so doing he makes incorrect statement s regarding the performance characteristics of the ASP. The intent of this paper is to rectify those erroneous representations and to clarif y several other issues raised by Zirin which might give the reader of his Letter an incorrect picture of the ASP.
