[daip] TASK IRING

[Israa]

Hi,
Good Day,

 I want to ask about  Task iring in AIPS. I want to make sure from input
information. My data have beam size 51.77" X 47.22" and task imhead give me

AIPS 1: Type       Pixels   Coord value     at Pixel     Coord incr
Rotat
AIPS 1: RA---SIN   256    15 22 00.000     *129.00*        -15.000
   0.00
AIPS 1: DEC--SIN  256    05 04 00.000     *129.00*
15.000            0.00
AIPS 1: FREQ         1      1.4127871E+09   1.00     2.4414062E+04    0.00
AIPS 1: STOKES       1    1.0000000E+00    1.00    1.0000000E+00    0.00
*Conv size*=  51.77 X  47.22   *Position angle*= -170.66

*My questions are about x, y - coordinate center wrt rference point in
pixels.*..Can I get it from task imhead (at pixel). I mean *129* or I have
to suppose (0,129) for x and y as well

*second question*, there are  radius inner ring ,  radius outer ring  and
width of each ring. In this case, I have to consider inner one is 0 right?
                                              outer one =51"   According to
beam size or what??
                                               width of each ring =within
beam size

Sorry for long questions, because I need to understand this task,


Best Regards,
Israa
