CAT_IN:

input catalog

INP_TYPE:

F if Fluxes, M if magnitudes

CAT_MAG:

AB or VEGA magnitude system of the input catalog (default AB)

CAT_FMT:

MEME or MMEE, to precise the order of value and error columns

CAT_LINES:

min,max range to subselect entries in the input catalog

ZPHOTLIB:

comma-separated list of template magnitude libraries without the suffix (to be found in $LEPHAREWORK/lib_mag)

ADD_EMLINES:

range of galaxy models for which considering emission lines contribution

EBV_RANGE:

E(B-V) min and max allowed in the library. Applied to all attenuation laws

Z_RANGE:

Z min and max allowed in the GALAXY library

PARA_OUT:

file listing the output keywords to be written on file (one keyword per line)

CAT_OUT:

output file name

CAT_TYPE:

LONG or SHORT, depending on whether zspec, context, and other columns are present after the magnitudes/fluxes and error columns

ERR_SCALE:

values to be added in quadrature to the errors in magnitude in each band, values separated by a comma

ERR_FACTOR:

values to scale the errors in flux (a single value for all bands)

GLB_CONTEXT:

global context to define the bands to be used in the fit

FORB_CONTEXT:

forbidden context to define the bands to be discarded from the fit

MAG_ABS:

min,max absolute magnitudes allowed for GAL type

MAG_ABS_QSO:

min,max absolute magnitudes allowed for QSO/AGN type

MAG_REF:

reference band to compute absolute magnitudes

NZ_PRIOR:

band to be used in the n(z) prior; a second band can be given in case the first one is absent in some objects

ZFIX:

fix z to a known redshift, in case one is interested in inferring the best template

Z_INTERP:

perform quadratic interpolation to refine best redshift solution

Z_METHOD:

which redshift solution, between best and pdf median, to use for physical parameter computation

DZ_WIN:

Window search for second peak

MIN_THRES:

lower threshold for second peak

SPEC_OUT:

output the best spectrum of each object

FIR_LIB:

dedicated far infrared synthetic magnitudes files

FIR_LMIN:

minimum value for lambda_mean/(1+z) (in microns) in FIR analysis

FIR_CONT:

context for the FIR bands to be used in the FIR fit

FIR_SCALE:

context for the FIR scale determination in the FIR fit

FIR_FREESCALE:

consider FIR scaling free

FIR_SUBSTELLAR:

substract the stellar component to the observed IR fluxes

MABS_METHOD:

method to compute absolute magnitudes (e.g. 1 use the most appropriated filter for observed flux, 3 the model)

MABS_CONTEXT:

context to decide which band can be used to derive the absolute magnitude in method 1

MABS_REF:

fixed filter used to derived all abs mag (if MABS_METHOD=2)

MABS_FILT:

list of fixed filters chosen to derive abs mag in all bands depending on the redshift bins defined in MABS_ZBIN (if MABS_METHOD=4)

MABS_ZBIN:

list of Redshift bins associated with MABS_FILT

RF_COLORS:

list of 4 band indexes out of which to compute the probability distribution of the 2 corresponding rest frame colors (default=-1 which means to not compute these color distributions)

M_REF:

band index for which to compute the rest frame absolute magnitude probability distribution

APPLY_SYSSHIFT:

list of values (equal to the number of bands) to add to the predicted magnitudes as zero-points (substracted to the observed magnitudes)

AUTO_ADAPT:

perform zero point auto adaptation based on the provided true redshifts

ADAPT_BAND:

band number for which to check magnitude range for auto adaptation

ADAPT_LIM:

min,max magnitude range for auto adaptation

ADAPT_ZBIN:

min,max value of the true redshifts used for auto adaptation of the zero points

PDZ_OUT:

output the PDF of each object

PDZ_TYPE:

list of the PDFs to output if PDZ_OUT is set

ADDITIONAL_MAG:

file basename (in $LEPHAREWORK/filt/) for the set of additional filters for which to compute magnitudes. Thus a pass to the LePHARE filter stage needs to have occurred on these filters.

LIMITS_ZBIN:

used to compute z_max. Redshifts used to split in N bins, separated by a coma. Need N+1 values (start with the minimum redshift).

LIMITS_MAPP_REF:

used to compute z_max. Band in which the absolute magnitude is computed

LIMITS_MAPP_SEL:

used to compute z_max. Give the selection band in each redshift bin. Need 1 or N values.

LIMITS_MAPP_CUT:

used to compute z_max. Apparent mag selection used in each redshift bin. Need 1 or N values

CHI2_OUT

Flag to output the chi2 value of each template (one file per source)
