getfilt: Extract Requested Filter Curve

In asgr/ProSpect: Professional Spectral Analysis Package

Extract Requested Filter Curve

Description

Returns a target named filter from the internal database of filters.

Usage

getfilt(filter)

Arguments

filter

Either filter name explictly built in to ProSpect, or an unambiguous grep match to one of the available filters in EAZY_filters, e.g. 'cfht_mega_u' unabmigously matches to the full filter name of 'megaprime/cfht_mega_u_cfh9301.dat'. You can also conveniently specify your own tophat with the filter name syntax 'tophat_lo_hi' where 'lo' and 'hi' corresponds to the lower and upper limits of the filter tophat in Angstrom. For the full set now available see options at filters, where all listed filers are accessible to the getfilt function (with the removal of the preceding "filt_"). The original set available was: Name Filter reference FUV GALEX FUV band NUV GALEX NUV band u Sloan u band g Sloan g band r Sloan r band i Sloan i band z Sloan z band u_VST VST u band g_VST VST g band r_VST VST r band i_VST VST i band z_VST VST z band g_HSC HSC g band r_HSC HSC r band i_HSC HSC i band z_HSC HSC z band Y_HSC HSC Y band Z VISTA Z band Y VISTA Y band J VISTA J band H VISTA H band K or Ks VISTA Ks band Z_UKIRT UKIRT Z band Y_UKIRT UKIRT Y band J_UKIRT UKIRT J band H_UKIRT UKIRT H band K_UKIRT UKIRT K band W1 Wise W1 band W2 Wise W2 band W3 Wise W3 band W4 Wise W4 band I1 Spitzer I1 band I2 Spitzer I2 band I3 Spitzer I3 band I4 Spitzer I4 band M24 Spitzer M24 band M70 Spitzer M70 band M160 Spitzer M160 band P70 Herschel PACS 70 band P100 Herschel PACS 100 band P160 Herschel PACS 160 band S250 Herschel Spire 250 band S350 Herschel Spire 350 band S500 Herschel Spire 500 band S450 JCMT SCUBA-2 450 band S850 JCMT SCUBA-2 850 band 1mm Aztec 1mm band 2mm Gizmo 2mm band Band9 ALMA Band 9 Band8 ALMA Band 8 Band7 ALMA Band 7 Band6 ALMA Band 6 Band5 ALMA Band 5 Band4 ALMA Band 4

Details

Returns a target named filter from the internal database of filters. Filters returned are of the type to be used when calculating AB magnitudes in bandpass.
Note LSST filters can also be accessed with "Rubin" (the preferred new shorthand name for the observatory).

Value

Two column matrix. First column is the wavelength in Angstrom and second column is the filter response.
