Doubts on the use of eazy-py

[gmazzolari]

1. How does eazy-py account for non detections (upper limits)?
   If I have one source that is out of the field for one specific observed band I have to put a value of Fn<-90 (NOT_OBS_THRESHOLD), but what if the source is undetected due to the fact that the observation is 'not deep enough' to reach the emission flux?
   I have in mind how HYPERZ works. In that case I have to tell the code the limiting magnitudes associated to each observation in each filter, and then, in case of undetection in a certain band (filter), there are different possible ways through which the code can account for these upper limits. In which way does eazy-py code account for them in the z_phot computation?

2. The prior magnitude file is applicable only if i have between my photometric points exactly the filter of the prior or is it enough having roughly the same filter band?
   That is: if I have the photometry of the K band from WIRCAM can I use the generic K prior contained in the given file 'prior_K_extend.dat'?

3. Is there a way not to combine the templates in during the analysis?
   Putting 1 in TEMPLATE_COMBOS in the file "zphot.param.default" doesn't work, moreover whatever value i put (2,45,True,Ciao ecc..) the code works giving the same results and always linearly combining all the templates (i see different components in the final plot). I didn't find any references to the parameter TEMPLATE_COMBOS neither in the photoz.py file.

4. Which is the origin and for which kind of objects are best suited the default templates "tweak_fsps_QSF_.." or "tweak_fsps_temp_kc13_.."?

Thank you

Hi @gmazzolari, did you find a workaround to solve the TEMPLATE_COMBOS issue?

I am having the same issue with TEMPLATE_COMBOS
