NOTE ="
1) IPAC HIRES iteration number = 1.
2) EXPOSURE_DURATION is the actual time spent observing the target.
The total duration of the observation is 764 seconds. It includes
time used to make attitude updates at the beginning and end of the
observation and is the difference in START_TIME and STOP_TIME.
3) B1950_RIGHT_ASCENSION and B1950_DECLINATION
refer to the right ascension and declination
assigned to the pixel at the center of the image.
4) North is up and East is to the left, based on SAMPLE_DISPLAY_DIRECTION
and SAMPLE_LINE_DIRECTION.5) ’RA---CAR‘ and ’DEC--CAR‘ values for
SAMPLING_PARAMETER_NAME indicate
a Plate Carree projection for right ascension and declination.
For more information see CALABRETTA&GREISEN02 and GREISEN&CALABRETTA02
6) NOT_APPLICABLE_CONSTANT of -9999.00 identifies an array element outside
the scan area
7) The effective beam sizes, provided by HIRES processing are
included below to illustrate how the effective spatial resolution
varies over the map by providing the dimensions of a rectangular
Gaussian profile of a resolution element at different locations
in the image.

20 Iterations)
(I,J) = IRAF pixel coordinates; Maj & Min = FWHM axes of Gaussian fit;
PosAng = position angle, East of North; Spike & Bckgrnd are model inputs;
number of pixels into which spike is smeared is on the order of Spike/Peak
