Exoplanets with MeerKAT

[cyriltasse]

Build a merged exoplanetary systems catalog from

https://exoplanet.eu/home/

https://exoplanetarchive.ipac.caltech.edu/

And a Gaia dr3 comparison stars catalog:

Query gaia stuff

ms2dynspec.py --ms <you.ms> --data DATA --model PREDICT_SUB --rad 1. --noff 30 --DoTar 0 --OutDirName Test --NCPU 90 --srclist test.txt

with test.txt being the file containing the info for your targets: Src_Label(str), ra(deg), dec(deg), Src_Type(str)

[bngcebetsha]

my test.txt looks like this:

Proxima_Cen,217.4289583,-62.6795000,S200

Ran:

python3 ms2dynspec.py --ms ../1556208112_20190425-J1429_6240-corr.ms --data CORRECTED_DATA --model MODEL_DATA --rad 1. --noff 30 --NCPU 90 --srclist proxima_source.txt

Returns

Will look to see if I can patch this tomorrow if @cyriltasse doesn't get to it first. Doesn't look like it will be too complicated.

[talonmyburgh]

@bngcebetsha are you on branch: MTilde_ASync_weights_mergeJones_merge

[bngcebetsha]

@talonmyburgh no, I'm on main

[talonmyburgh]

Use the branch I mentioned there and try again - I am unfortunately having connection issues with SARAO computers that I'm waiting on IT to solve :)

[bngcebetsha]

The problem I am now getting is caused by my MS - something I will need to sort out:

permission to fork repo so I can make changes to the branch @cyriltasse ? I updated a few imports

[cyriltasse]

Hi thanks, I had a similar problem lately but I fixed it, @bngcebetsha what branch are you using?

[bngcebetsha]

Hi thanks, I had a similar problem lately but I fixed it, @bngcebetsha what branch are you using?

@cyriltasse thanks for your response, I am running MTilde_ASync_weights_mergeJones_merge branch

[cyriltasse]

Can you try with SplitCatalog branch?

[bngcebetsha]

SplitCatalog

I still get the time resolution issue I reported here - https://github.com/cyriltasse/DynSpecMS/issues/23#issuecomment-2061463083

thanks I think I should have a closer look at this myself.

[bngcebetsha]

@cyriltasse - I was wondering when you will have time to chat about this method - https://github.com/cyriltasse/DynSpecMS/blob/fd32cac4d907383b8c9df4ff3e121fba64d604d1/ClassDynSpecMS.py#L989

Its raising an exception during processing.

[o-smirnov]

@bngcebetsha I can see this method appeared in later DDF branches. Try the UseAPP_kMS_MeerKLASS branch for instance.

[cyriltasse]

Yeah that could well be that you need a more recent version of DDFacet... @bngcebetsha maybe I can give you a singularity image that as all up to date branches?

[bngcebetsha]

@cyriltasse that would be nice, thanks @o-smirnov . I forked and hacked away at DynSpecMS till it produced something. I still need to understand the output fits files I got. Thanks for all the help and the tool
