IPAC (Log(g)) based on class of features 1-Fs/Fc. Modeled with BT-Settl 2011-13

Introduction

After the analysis carried out for M stars within the IPAC analysis, we wnat to apply the band I features discovered there to estimate physical parameters from IRTF dataset. Target values came from Table III from Cesetti et al.

Target T will be between 2000 K and 4200 K

Prediction for Temperature

We will use the I-Band according to GA models noised by SNR=50 and SNR=10 as well as the features proposed by Cestti et al. also noised by SNR=50 and SNR=10.

Distance $ ^2 $ between spectra

Let’s find the closest spectra at different SNR ratio per IPAC spectum.

Closest spectrum for BT-Settl SNR=50

minchid=function(x,lib){
  chid=function(x,y){
    if ( nrow(x$data[[1]]) == nrow(y$data[[1]])) {
      return(sum((x$data[[1]][,2]-y$data[[1]][,2])^2)/nrow(x$data[[1]]))
    } else {
      return (5000) # Enormous distance as it is not valid
    }
  }
  ldist=ldply(lib,chid,x)
  idx = which.min(ldist[,1])[1]
  res = data.frame(T=lib[[idx]]$stellarp[1],logg=lib[[idx]]$stellarp[2],
                   met=lib[[idx]]$stellarp[3],name=lib[[idx]]$name,
                   dist=ldist[idx,1])
  return(res)
}
