The main limitations of these data are:

1. Videos are assembled in a constant Carrington rotation frame so, BMRs may drift within the video due to differential rotation.



2. Many videos have gaps and thus, do not have a constant cadence. We addressed this by interpolating the missing frames. In these videos we do not include interpolated frames
   .

The Active Region (AR) magnetic evolution videos are created by -

1. Projecting full-disc line-of-sight magnetograms into Carrington grid


2. Dividing the projected maps into 15 degrees x 15 degrees non-overlapping patches. Each patch is sampled into 90 pixels x 90 pixels resulting into pixel scale of (1/6) degree


3. Stacking a set of consecutive frames covering about half a solar rotation tied to each AR from Bipolar Active Region Detection (BARD) catalogue

1. 'NAXIS1' represents number of x-pixels


2. 'NAXIS2' represents number of y-pixels


3. 'NAXIS3' represents number of frames


4. 'TIMEXXXX' represents the time stamp for frame XXXX in YYYY-MM-DDTHH:MM:SS format


5. 'CRVAL1' represents the starting Carrington Longitude (degrees) for each video


6. 'CRVAL2' represents the starting Latitude (degrees) for each video
