messy sky #12

Hi,

This is a great package and I find it to be helpful. I am trying to plot this one target "Hen 2-73" by using the following line of command:

python tpfplotter.py Hen_2-73 --COORD 177.1587316,-65.143457 --maglim 2 --gid 5332582092827700224 --gmag 17.545

I am using "--maglim 2'' as I find the default maglim to be too high and that there will be too much dots covering across the sky. However, even if I am using maglim 2, the plot still appears to be way too messy

Is there any way I can modify this to make the plot better? perhaps by making the circles smaller? Also, do I have the option to let it plot the aperture mask I want by defining my own aperture mask, or just not to include any aperture mask in the plot at all?

I am also curious if there are any possibilities not to include the numbers marked white on the plot, and if the pixel number can go increasingly from right to left as how it should be instead of increasing from right to left. Many thanks.

Best, Harry

The problem in this case is that your target is very much fainter than the vast majority of the targets in the field, which BTW is very crowded. Hence, in this case tpfplotter is not useful in this case as it is meant to show the contamination of the field around your target to check whether your TESS photometry is useful. The answer is that in this case your field is very crowded and definitively the TESS photometry is useless. Sorry but I cannot help more on this.
