PCA program is ready to run:

 

I use "pbh_dr7qANDhw10_dr7qzHW" catalogue. I read M_i and redshift (HW) and plate mjd and fiber and SDSS_J2000_ID from this file.

the program min3_qev.sm is adjusted to record  "Mibin" and "zedbin" as well as all 50 eigenspectra in order from 0 to 40 in vector "qsoEigCo" and the reduced-chi2.

I also record the reconstructed file. I will use this to calculate the MgII-mass later.
