WBPP using the value of DEC within light frames when using Group Keyword

Rick Laird

I use sub directories to seperate different light frame sessions. 

i.e 

  M3

DEC_2023

( zero files)

JAN_2024

(20 files)

I was adding light frames to WBPP with two values in the Group Keywork list. 

DEC and JAN

When WBPP added the 20 JAN files and found no files with DEC in the path so it the script then looked up DEC in the FITTS header of the files seperated the files by DEC. Which in my case with slightly different due to dithering. 

I ahve been using Grouping keyword for jsut the file path but turns out it can be used to group based on any attribute in the FITTS header too. 

Maybe something like FOCPOS  as you see in the third screenshot. 

More powerful than I thought. But it did confuse me for a while. 

I thought I would share with this group.

Yep. 

I know my videos are long. 

However, I do explain in the WBPP series all of this information. 

Many beginners are confused by metadata in file headers...so I have highlighted the organizational use of folders (paths). However, if you review this you will see I full explain keywords and how to take advantage of them:

and Demonstrations:

A recent example of importance of understand keywords in headers is the GAIN and OFFSET keywords. People are mixing their GAIN and OFFSET data...and making a mess. Applying Grouping Keywords of GAIN and OFFSET completely solves this issue.
