Examples

% get a MARX-simulated Chandra/ACIS PSF at mono energy or spectrum-weighted 
% for a given position and roll angle on a given Chandra/ACIS chip (detector), 
% whose number is the first argument of the function:
P = VO.Chandra.getACIS_PSF(0, 'Energy', 2.5, 'PosX', 124, 'PosY', 876); 
%
RollAngle = 53; 
P = VO.Chandra.getACIS_PSF(1, 'Energy', 3.2, 'PosX', 124, 'PosY', 876, 'RollAngle', RollAngle);
%
En = 1:10; Sp = [En; En.^-2]';
P = VO.Chandra.getACIS_PSF(3,'Spec', Sp, 'PosX', 100, 'PosY', 301);
