5.15. div

Performs division on the FitsArray object.

FitsArray.div(self, other: Self | Fits | float | int | List[Fits | float | int], output: str | None = None) → Self

Performs division on the FitsArray object.

Notes

This method can divide numeric values, other Fits objects, or lists of numeric values or FitsArray objects.

  • If other is numeric, each element of the matrix will be divided by that number.

  • If other is another Fits object, element-wise division will be performed.

  • If other is a list of numeric values, the first value will be applied to each matrix. The number of elements in the list must equal the number of elements in the FitsArray.

  • If other is another FitsArray, element-wise division will be applied. The number of elements in both FitsArray objects must be equal.

Parameters

otherUnion[Self, Fits, float, int, List[Union[Fits, float, int]]]

Either a FitsArray object, list of floats, list of integers, Fits object, float, or integer.

outputOptional[str]

New path to save the files.

Returns

FitsArray

A new FitsArray object containing the saved FITS files.

Raises

NumberOfElementError

Raised when the length of other is incorrect.

5.15.1. Example:

from myraflib import FitsArray, Fits

fa = FitsArray.sample()
fa_2 = FitsArray.sample()

fits = Fits.sample()

divided_fa_1 = fa.div(10)
divided_fa_2 = fa.div(fits)
divided_fa_3 = fa.div([1, 2, 3, 4, 5, 6, 7, 8, 9, 10])
divided_fa_4 = fa.div([Fits.sample() for _ in range(10)])
divided_fa_5 = fa.div(fa_2)

divided_fa_6 = fa / 10
divided_fa_7 = fa / fits
divided_fa_8 = fa / [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
divided_fa_9 = fa / [Fits.sample() for _ in range(10)]
divided_fa_10 = fa / fa_2
