Multi-Band Synchronization

Getting synchronized multi-band cutouts took a full week to solve. The trick, which seems so obvious now, was to calculate the bounding box just once using a reference coordinate system (WCS) and then apply that same box to all the different filter bands (g-band, r-band, etc.).


Before this, I was wrestling with cases where the g-band had data but the r-band would throw an exception. The goal was to "handle missing bands gracefully." When I asked for a definition of "gracefully," we settled on a simple one: "don't crash." Mission accomplished.

Damn couldn't believe I got in again.

I was glued to reddit and the website the whole time for 4 hours. The results came out later than UTC 18:00 and didn't get the mail until four hours beyond the scheduled time.  None of my friends got in, so was kinda anticipating a rejection too, but to my surprise I got in. I am really excited to go through this journey again. It would be amazing.

Proposal Sent! The Waiting Game Begins...

 Drafted, revised, got feedback (mentally, from myself mostly haha), polished, and finally hit submit on the proposal!

Fingers, toes, everything crossed! Whatever happens, learned a ton already.

Drafting sections on objectives, methodology, the timeline... This is where the deep dive into the LSST pipeline docs and the project description really matters.
