Just an update. When using 'aststatistics' with the option '--sky' the same problem happen. Note the wanted name of the output image and the final written one:

$ aststatistics image.fits -h0 --sky --output=outputsky.fits
Statistics (GNU Astronomy Utilities) 0.14.86-56f9
Estimating Sky (reference value) and its STD.
  - Using 16 CPU threads.
  - Input: image.fits (hdu: 0)
  - Sky and its STD found on 135/8217 tiles.           0.095662 seconds
  - All blank tiles filled (interplated).              0.157079 seconds
  - Smoothed Sky and Sky STD values on tiles.          0.003965 seconds
  - Sky and its STD written to 'outputsky_sky.fits'.
Completed in: 0.495112 seconds

When running NoiseChisel with the option '--checksky', it finishes the execution and give an output that has the same name as the input image but adding the suffix '_sky.fits'. The important point is that it completely ignores the name provided by the user with the option '--output'. This is not good if the desired output is the actual '_sky.fits' image but with any other name (for example in an automatic pipeline).

The main idea of the proposed solution would be this (previously discussed with Mohammad): when the following conditions are met, NoiseChisel (or Segment or Statistics) should use the file given to '--output' for the check image:

1) only one check image/table is requested, and
2) '--continueaftercheck' is not given, and
3) '--output' is given
