Read the output of the DOLPHOT photometry package into easier-to- use data structures.
Return value
This function outputs an array of structures, one for each star. The structure has the following fields: extension, chip, xpos, ypos, chi, sn, sharpness, roundness, majoraxis, crowding, objtype, counts[N], background[N], magnitude[N], magerr[N], imgchi[N], imgsn[N], imgsharpness[N], imgroundness[N], imgcrowding[N], fwhm[N], ellipticity[N], PSFa[N], PSFb[N], PSFc[N], errflag[N]. If NHSTFILTERS gt 0 then magnitude[N] is replaced by instmag[N] and transfmag[N]. If /V2 is set, then fwhm[N], ellipticity[N], PSFa[N], PSFb[N] and PSFc[N] are replaced with ctcorr[N] and dctcorr[N]. N is Nimg plus NHSTFILTERS. The HST filter information comes first.
Parameters
- filename in
Name of DOLPHOT output file
- nimg in
Number of images
Keywords
- nhstfilters in
If this is set to a number greater than 0, the output is assumed to have been generated using DOLPHOT/ACS or DOLPHOT/WFC3, and to have NHSTFILTERS photometry blocks at the beginning that give the combined results of each filter. The output is also assumed to both have instrumental and transformed magnitudes.
- v2 in
If /V2 set, then read in DOLPHOT 2 output (slightly changed from version 1)
