Hello.
Among the calibration files of Pier6, there is a point I would like to confirm about P6-Darks-Jul2021-10s.7z.
When I unzip this file, I see the Lum characters in the filename.

Is this the right Dark?
The result was strange when I used this.

Thank you

Hello, yes this was my mistake when collecting the darks. It is very easy with this camera to forget to set it to Darks as it has no shutter system. The frames are still dark frames but do show a filter name in the fits header as light frames. 
If you are using an automated calibration and stacking some software will get the darks and light frames confused. This can be easily fixed by renaming in the fits header. Highlight the offending name, fill out the correct information and click replace. 
Hope this helps you

Thank you for your quick response.
First of all, I apologize for the fact that the content written last time was incorrect.

It is FLAT file that contains LUM characters. Not DARK
The file name is from (1) to (20) as shown by Flat-Lum (1) .Fit.
When I see Fits Header, the image type seems to be correct.
Because it is FLAT.
Is this FLAT file for LUM?

That is perfectly fine - as it's a One shot Color with no filters, the filter is just called LUM

Kind regards, Phil.
