censoreddata's Introduction

CensoredData

How can we make the best use of non-detections and noisy data when we don't believe the uncertainty or upper limit informaiton being reported by the data provider?

data:

  • mira_sims: light curves for simulated mira variables. LCs are of ASAS 235627-4947.2 with varying fractions of the original flux, e.g., 1, 0.5, 0.25, 0.01

  • miras: ASAS light curves for the 1720 mira candidates, with non-detections denoted with 29.999

  • mira_features.dat: features for 1720 mira candidates, including all Lomb-Scargle and non-LS features

  • rrl: ASAS light curves for the 1029 RR Lyrae, FM candidates, with non-detections denoted with 29.999

  • rrl_features.dat: features for 1029 RR Lyrae, FM candidates, including all Lomb-Scargle and non-LS features.

censoreddata's Issues

Validate the estimated Mira P-A relationship

Further astrophysical validation of the estimated Mira P-A relationship. Maybe split the LMC objects from the galactic plane Miras to see if any strong relationship pops out.
Other papers omit Miras where no trough in the LC was observed; we should compare our inferences to theirs (Hipparcos, NSVS, OGLE & MACHO data, papers in repo).

methods need names!

"Censored LS" and "Lomb-Scargle" are not good names; we should be calling them something like:

  • Traditional Method
  • Ignore-Missing-Data
  • Detection-Only Model
  • ?

and

  • Insane Robot Method
  • Flexible Censoring Model
  • Non-detection model

Then, once we decide on names, we should put in an issue to flow those names through the document and the figures.

intro back to joey

I noticed that @joeyrichar edited Section 1 before he had sign-off from me. But no conflicts hit, so all is good. I am now officially handing it back to you.

@joeyrichar the figures you put in the paper look GREAT. Let's keep it up, because we are only days from completion.

Write up results for 2500 ASAS Miras

Write up results for all 2538 Miras that were fit using Censoring LS code. Preliminary figures have been made, but a full write-up needs to be done.
Include comparison to the periods provided by ASAS for all the Miras

make all to-do items into github issues

Joey:

I just "issued" myself with the to-do items we agreed on way back in August. Can you open issues and assign them for the remaining to-do items? I am also going to set up a "milestone" for this paper.

citations / references needed

@dfm, if you want to re-earn your co-authorship, could you go through the intro and turn the CITE comments into citations? It also requires a bit of digging, because we need to cite some kind of weak lensing paper (maybe by Bernstein? maybe ask Marshall?) that says that you have to work at image level. Maybe there is no clear reference...?
