pydl.pydlspec2d.spec1d.spec_append(spec1, spec2, pixshift=0)[source]

Append the array spec2 to the array spec1 & return a new array.

If the dimension of these arrays is the same, then append as [spec1,spec2]. If not, increase the size of the smaller array & fill with zeros.

spec1, spec2numpy.ndarray

Append spec2 to spec1.

pixshiftint, optional

If pixshift is set to a positive integer, spec2 will be padded with pixshift zeros on the left side. If pixshift is set to a negative integer, spec1 will be padded with abs(pixshift) zeros on the left side. If not set, all zeros will be padded on the right side.


A new array containing both spec1 and spec2.
