For the Atlas A2 training product/Atlas A2 inference product, the value does not need to be an even number or aligned. For the Atlas A3 training product/Atlas A3 inference product, the value does not need to be an even number or aligned.
right	Int, right offset. For the Atlas training product, the value must be an odd number. For the Atlas inference product, the value does not need to be an odd number. For the Atlas A2 training product/Atlas A2 inference product, the value does not need to be an odd number. For the Atlas A3 training product/Atlas A3 inference product, the value does not need to be an odd number.
top	Int, top offset. For the Atlas training product, the value must be an even number. For the Atlas inference product, the value does not need to be an even number. For the Atlas A2 training product/Atlas A2 inference product, the value does not need to be an even number. For the Atlas A3 training product/Atlas A3 inference product, the value does not need to be an even number.
bottom	Int, bottom offset. For the Atlas training product, the value must be an odd number. For the Atlas inference product, the value does not need to be an odd number.
