naming convention for lensed host galaxies #89

Open mpwiesner opened 4 years ago

mpwiesner commented 4 years ago

Is there a preferred naming convention for lensed host galaxy FITS stamps? Right now they are named like this: lens_ID+lensed_u_band_magnitude+lensed_g_band_magnitude+lensed_r_band_magnitude+lensed_i_band_magnitude+lensed_z_band_magnitude+lensed_y_band_magnitude_bulge/disk.fits

Example: 9993181_24.528840367986316_24.20642333936395_24.074635430660926_24.02940766644763_24.070640392595934_24.188802301179077_bulge.fits

These names will get put in a list of FITS stamps by the script and somewhere ImSim will have to parse these names.

By lensed_u_band_magnitude do you mean lensed u-band magNorm value? Is it just the u-band magNorm + magnification?

mpwiesner commented 4 years ago

@jbkalmbach yes that is correct. Is this useful to have in the filename? If not, do you have an idea what filenames should look like?

Phosim Ids are just strings right? So I was anticipating changing DDF lensed object ids from integers to just strings with the form agn_host_"dc2_sys_id"_"image_number". So it would look something like agn_host_0_0 or sne_host_10_1. Because I think we should be able to get those magnitudes out of the truth catalogs right? What do you think?
