Plates From Münster Flare Star Survey 1986-1991 From 1986 through 1991, the Astronomical Institute of Münster University performed a search for flare stars in several southern associations and open stellar clusters using the GPO telescope (d=40 cm, WFPDB identifier ESO040); the fields suveyed include Coalsack, M42, B228 Lup, the Chameleon T1 association, omicron Vel cluster, R CrA association, the Pipe nebula (B59 Oph), and the Sco-Oph association. This was done primarily through multiple exposures. The files published here are plate scans done in 2017. The obscore collection name for these files is Muenster Flare Survey. 2017-10-04T12:21:00Z 1000 flare-stars uv-ceti-stars astrophotography Tsvetkov, M. 40cm GPO ESO La Silla 1990IAUS..137...85A Research Catalog ivo://org.gavo.dc/hppunion/q/im Optical //obscore#publishSIAPmdlpub_didtsdlpub_didflare_survey.dat application/x-votable+xml;content=datalink Datalink 44608 48452.3 3/577,590,667,671 4/1338-1339,1342,1425,1428,1802-1803,1824-1826,2320,2326-2327,2329,2332-2333,2355,2364,2366,2370,2570,2601-2603,2677,2679-2680,2682-2683,2688-2690,2772,2982-2983,2988-2989,2994,3000 2.79781e-19 5.84249e-19 "\schema.data" @PLATENUM.lstrip('0') "EMULSION" { "KODAKIIa0": "KODAKIIaO", "KODAKIIaO": "KODAKIIaO", "KODAK IIaO": "KODAKIIaO", "KODAK 098": "KODAK098", "KODAK 098": "KODAK098", "KODAK IIIaJ": "KODAK IIIaJ", "KODAK IIa0": "KODAKIIaO", "": None, } "FILTER" { "RG630": "RG630", "R630":"RG630", "": None, } @bandpass = "+".join( a for a in [@EMULSION, @FILTER] if a is not None) if @platenum in set(['13819', '13780', '13793']): @kind = "TRACK" elif @MULTIEXP>1: @kind = "MULTIPLE" else: @kind = "DIRECT" @title = "flare survey %s %s %s"%(@OBJECT, @kind, @DATE_OBS) @bandpass parseISODT(@DATE_OBS+"T"+@TIME_OBS) "C" @title False if "CTYPE1" not in vars: result["centerAlpha"] = hmsToDeg(@RA, ":") result["centerDelta"] = dmsToDeg(@DEC, ":") result["pixelSize"] = [@NAXIS1, @NAXIS2] result["pixelScale"] = [@FOV1/@NAXIS1, @FOV2/@NAXIS2] result["nAxes"] = 2 result["wcs_equinox"] = 2000.0 start_time = parseISODT(@DATE_OBS+"T"+@TIME_OBS) end_time = parseISODT(@DATE_OBS+"T"+@TIME_END) if start_time>end_time: end_time = end_time+datetime.timedelta(days=1) @obs_duration = (end_time-start_time).total_seconds() A common meta maker for the datalink services, linking to ancillary files by plate number. stem = descriptor.accref.split("/")[-1].split(".")[0] yield descriptor.makeLinkFromFile( "data/static/photos/{}.jpg".format(stem), semantics="#preview-image", description="Mid-resolution plate photo.", contentQualifier="#image") yield descriptor.makeLinkFromFile( "data/static/envelopes/{}e.jpg".format(stem), semantics="#documentation", description="Photo of the plate envelope.", contentQualifier="#image") data/static Münster Flares Time Series Datalink This service produces datalinks for multiple-epoch exposures of the Münster flare survey plates.
