standard=l053 (had to extract it on panisse cos standard wouldn't work) arc= 055 ------------------------------------------------------------------------- sn974 #58 59 extracted one object (but one frame shows shoulder) >> gal has z=0.58 (OII, Hg, G, OIII?) not sure if there's SN signal there or not OK if UV deficit can begin further to blue >> sn974cc_sum ------------------------------------------------------------------------- sn973 #65 66 extracted one object (possibly shoulder in 065 though) strong emission line in main object. Maybe another line too. ***** Try extracting shoulder >> sn973cc_sum ------------------------------------------------------------------------- sn9722 #73 74 many objects in slit. Target is the one above bright one near centre. 183 = gal with narrow lines 192 = target - blue, featureless object ? 229 = gal at z=0.6 ? (H&K + break) >> sn9722_sum (sn only) ------------------------------------------------------------------------- sn9748 #81 82 83 84 extracted one object. z=0.59 noisy galaxy (OII + many absorption features) Type Ia SN spectrum visible but not strong... * Try plotting this with aredshift, check z >> sn9748cc_comb ------------------------------------------------------------------------- sn9733 #90 91 2 objects. not sure which is which blended slightly but separable. blending worse on 91. 195 (ap1) z=0.37 galaxy (OII, OIII etc). SN visible too we think ! 199 (ap2) z=0.71 galaxy (H & K) >> sn9733cc_sum ------------------------------------------------------------------------- sn9732 #97 98 99 extracted one object z=0.43 (OII, OIII, Hb etc). Particularly weak SNish wiggles, plausibly Ia. Two big broad features at right place. Not much else is easy to tell. >> sn9732cc_comb ------------------------------------------------------------------------- sn9738 #105 106 107 extracted one object z=0.47 (OII, H&K) looks like SN Ia >> sn9738cc_comb ------------------------------------------------------------------------- NIGHT 2 ------------------------------------------------------------------------- sn972 #166, 167 168 ap1: junk ap2: Target close to brighter galaxy (slightly merged) ap3: Neighbour galaxy is z=0.76 Probable SN Ia light with z=0.54 or z=0.75, leaning towards 0.75 SNIa ? - possibly Ca H abs line visible at z=0.75 ? ? emission line @7976.5 ? >> sn972cc_comb ------------------------------------------------------------------------- sn975 #174 175 Two objects close together 192 (ap1)- target. z=0.62 (H&K + break) likely SN there too. 202 (ap2) featureless galaxy ? >> sn975cc_sum ------------------------------------------------------------------------- sn970 z=0.18 (Lidman says) [check we've got 970 & 971 right way round] ***** verify this >> sn970_eso ---------------------------------------------------------------------- sn971 - z=0.53 (H&K) - looks right to me. weak SNIa humps line up at this z. >> sn971_eso ---------------------------------------------------------------------- sn976 z=0.55? (lidman says). looks reasonable to me. z just under 0.55, based only on SN; no abs lines yet identified >> sn976_eso ---------------------------------------------------------------------- sn9742 z=0.4 we think. maybe H&K & G ? - SN features there. >> sn9742_eso ---------------------------------------------------------------------- sn9710 uncertain SN match - 5000A matches but no SI abs. z=0.4 (Lidman) Odd -- maybe matches SN in z=0.35 to z=0.4 range. Some features are mucked up, then. Doesn't look like AGN. ***** ASK peter about this spectrum. ***** Overplot with sn9733 for comparison >> sn9710_eso ------------------------------------------------------------------------- sn9749 #181, 182, 183 lots of objects in the slit. One is z=0.91 gal (H&K) object is at 192. featureless blue object ? * If lightcurve does anything, come back and try to find the redshfit from putative absorption lines >> sn9749cc_comb ------------------------------------------------------------------------- sn9760 #189 190 2 objects close together 189 (ap 1) - neighbour galaxy z=0.65 (H&K + break) 192 (ap 2) - SN : z=0.65 we think. H&K visible too ? (at first we thought 0.4, but are convinced now, at 5:30 AM at 14,000', that it's 0.65) >> sn9760cc_sum -------------------------------------------------------------------------- sn9740 #200 201 one object - emission lines. -- Mystery object with random broad lines. QSO @z=0.41 ?? (hg OII ?) Not a Ia anyway ! Curves up strongly to the blue. Makes Isobel sad. >> sn9740cc (run 200 only- 201 was stopped early) ------------------------------------------------------------------------- sn9716 #205 206 one object QSO @z=0.9 (MgII, OII, OIII?) Not a Ia. >> sn9716cc_sum -------------------------------------------------------------------------- sn9739 Beautiful SNIa spectrum, classic, poster child, paint on the side of AC transit busses. Ask for money for dedicated 4m telescope. z=0.61 (OII, OIII) >> sn9739cc_comb ----------------------------------------------------------------------
