- dim_azimuthTime :
- max dimension of azimuthTime for a swath
- dim_slantRangeTime :
- max dimension of slantRangeTime for a swath
- comment :
- The antenna pattern data set record contains a list of vectors of the antenna elevation pattern values that have been updated along track and used to correct the radiometry during image processing.
- example :
- for example, if swath Y is smaller than swath X, user has to remove nan to get the dims of the swath

- dim_azimuthTime :
- max dimension of azimuthTime for a swath
- dim_slantRangeTime :
- max dimension of slantRangeTime for a swath
- comment :
- The antenna pattern data set record contains a list of vectors of the antenna elevation pattern values that have been updated along track and used to correct the radiometry during image processing.
- example :
- for example, if swath Y is smaller than swath X, user has to remove nan to get the dims of the swath
