Chatziargyriou Eleftheria | Good morning! I get more and more busy with the exams, but luckily it'll be over in just over a week. I planned on adding a few more missing parameters for czml3, but I think it would be best adressed on a separate PR. After a couple more additions, I'll be ready to push the refactored extractor | 09:18:07 |
astrojuanlu | excellent! ping me if you have any issues :) | 09:18:41 |
Chatziargyriou Eleftheria | Will do 😊 | 09:19:34 |

astrojuanlu | jorgepiloto: did you see anything meaningful with the Lambert solutions? | 08:33:18 |
astrojuanlu | Chatziargyriou Eleftheria already told me she's about to publish new properties for czml3 | 08:33:35 |
jorgepiloto | Sorry, I did not see the message till now. Not sure why notifications do not show in my devices 😕 | 09:19:23 |
jorgepiloto | I also found that the plot T vs x for multiple revolutions is shown in Battin 1999 | 09:22:20 |
astrojuanlu | ah, that's perfect! I have that book in the office, I can check it out later | 09:26:51 |
jorgepiloto | I am still checking the whole algorithm and the subroutines from the iod.izzo module. But these minor error are strange since most of solutions seem to converge to the good ones 🤔 | 09:28:37 |

astrojuanlu | make sure you configured your notifications properly :) | 09:29:02 |
astrojuanlu | In reply to @jorgepiloto:matrix.org I am still checking the whole algorithm and the subroutines from the iod.izzo module. But these minor error are strange since most of solutions seem to converge to the good ones 🤔 interesting! if in doubt, I think https://github.com/esa/pykep must have an alternative implementation (because it's Dario Izzo astrodynamics library) | 09:30:33 |
astrojuanlu | or probably you can ask in #gitter_esa=2Fpykep:matrix.org | 09:30:46 |
astrojuanlu | (however, make sure you don't translate code from pykep to poliastro because pykep is GPL) | 09:31:27 |
jorgepiloto | Oh! I had dissabled notifications from groups... This is strange, I did not changed anything. Anyway, it seem like they are working again 👍️
If I get stucked with this issue I will ask is the pykep group. I am going to check the pykep package. Thanks! 🚀 | 09:35:34 |
jorgepiloto | This is the C code implementation of the Izzo's algorithm in pykep package: https://github.com/esa/pykep/blob/master/src/lambert_problem.cpp
I will compare it against poliastro's one and also check everything with the original paper
| 09:44:05 |
astrojuanlu | or maybe, if you manage to install it jorgepiloto (there's conda install pykep -c conda-forge if you need it), maybe you can compare the output first | 09:56:54 |
astrojuanlu | probably it's easy than looking at lines of code | 09:57:06 |
astrojuanlu | your call :) | 09:57:21 |
jorgepiloto | I think I prefer your solution 😂😅 | 10:28:02 |
jorgepiloto | Hahaha Hope to advance faster in this issue with all previous suggestions 😊 | 10:28:30 |

astrojuanlu | current status:
- following up with Chatziargyriou Eleftheria about validation in czml3. type validation is a bit anti-pythonic. I tried using MyPy but at some point it was getting tedious, also see https://github.com/poliastro/czml3/commit/a9b153e. then, interestingly there are no well-maintained Python libraries to validate css input (we saw cssutils but it's been abandoned since 2017)
- finishing the
Orbit.set_attractor method with jorgepiloto - we reached a point where we are satisfied with the API, so we should have it soon
later on in the evening I will go to the Python Barcelona Meetup :) have a nice day!

astrojuanlu | GitHub is experiencing issues https://www.githubstatus.com/incidents/qjhqlf52nw6n | 08:53:26 |
astrojuanlu | solved :) | 13:03:40 |
astrojuanlu | three weeks to poliastro 0.13 beta 1! no more features after that point | 13:04:03 |

astrojuanlu | Good afternoon shreyasbapat 😛 | 06:18:21 |
