KiDS DR3: Inconsistency among structural parameters of different 2DPHOT runs #1

Closed nrnapolita closed 6 years ago

nrnapolita commented 7 years ago

Nivya and Fedor Check whether the input of the different results were different.

nrnapolita commented 7 years ago

1) DR3 are ran again 2) NR reports the status of the DR3 run and 32 tiles in r-band have been finished in ~1.5 days!! 3) problem with the computing time? 4) because of that NR will produce a comparison between the 32 tiles and the previous ESO extraction, we see the scatter plots and decide if contibue with theb new ESO-DR3 run... TBD in the next 2 days! [Meanwhile run the Dr1/2 tiles, to be done anyways]

Here is the delta_param vs param_old plots for different parameters [re, n, q, PA, and MAG_2DPHOT]. delta_param is param_new-param_old delta_n.pdf delta_q.pdf delta_re.pdf delta_PA.pdf

ctortora commented 6 years ago

Dear all,

I do not know who is receiving this email,

but what do we do with these results? There is some scatter, I would quntify better it? Is it too strong?

And how we decide what fit is better? The previous or the last one?

Cheers,

I asked Nivya to quantify better this scatter. One way is to add mean + STD (plus the nominal value of the scatter). These have to be compared to the relative scatter found in the simulation test.

ctortora commented 6 years ago

Are the new DR3 values identical to the latest DR3 values you provided to me?

Here is another plot with the difference in parameters for two DR3 run. Mean values are given along with the single datapoints. Error bars show the standard deviation in bins of parameter plotted on x axis. The numbers given are the standard deviation in each bin. KIDS_DR3_OLD_NEW.pdf

Dear Nivya and all,

Some questions:

nrnapolita commented 6 years ago

Before we close this issue we need to check whether we can use the old parameters from DR1 and DR2 fields. CT will do a check on the effect on colour gradients

nrnapolita commented 6 years ago

CT & NR: for the tiles where we have both DR3 extraction and DR1-2, check the impact on the colours and the internal consistency of their own extraction (are they from the same epoch? Were there multiple extractions?)

KiaraSpin commented 6 years ago

Group Meeting 18/12 Nyvia is still working on the catalogs. She will passe them to Crescenzo in the next days

KiaraSpin commented 6 years ago

GM 15/01/2018: Crescenzo has everything he needs from Nyvia. He will start working on the color gradients. We will go for DR3. For all the tiles we have r,g,i all the parameters (S and N) - g,i from previous run - The problem with r-band was that we lost something, so we did it again.

About DR1 and DR2. Are them okay? Check that relations between the structure parameters stay the same. (We did already this check with DR3-epoch1 and DR3-epoch2) -> AI Crescenzo: Check that there is no systematic difference.

KiaraSpin commented 6 years ago

GM 29/01 We should try to close this issue as quick as possible. AI Crescenzo: Working on this during the week (starting on wed). In particular, 1-to-1 comparison between DR1/DR2 parameters and DR3 parameters.

KiaraSpin commented 6 years ago

GM 12/02 This issue is closed because we decided to run 2DPHOT on DR3.

However we have currently a PROBLEM WITH 2DPHOT. It points to some directories of Francesco machine. He needs to take actions.
