Made a bias frame bias70_79. This has been overscan corrected. ---------------------------------------------------------------- SN969 Done roughly on 18th mar 96 >> 969c - only overscan corrected (not zero corrected or flattened) also used 032_sky for W calibration - but lines shifted. reidentify sky lines in 043. used old extractions but re-W calibrated them using 043_sky F calib: use 049sens >> 969c.imh >> 969.asc Problem with 5577 ? just maybe H & K @ z=0.50 ? OR 0.34 ? --------------------------------------------------------------- SN963 Done roughly on 18th mar 96 >> 963c 18mar0032 OZF corrected - flat was 031_pix 2nd go, Apr 3rd 96. 18mar0035 - use flat 031 too. extracted >> 035_2x ? maybe two objects ? having trouble with trace. >> 032_2x W calib - used 030arc F calib - use 049sens - (really should have flat for this, but used O corrected image - not Z corrected either). (only good from 3400 to 9500) >> 963_2c >> 963.asc > sn963_mmt.asc (I think) Maybe lines ??

Use (frame #34) extracted >> 2 objects 028_2x ap #1 bright thing off center ap #2 SN 031_2x only one object now. W calib: use 035arc F claib: 023sens scopied 028_2c ap#2 to 028_2c_ap2. NB had to renumber aperture in scopy, otherwise it wont combine properly with 031. combined (using scombine) 028_2c_ap2 with 031_2c >> 962_2c (SN spectrum - other bright object is only in 028_2c) possible OIII, OII & Hb in SN spectrum at z=0.45 ? ascii file: 962_2c.asc ------------------------------------------------- SN9621 19mar0039 was overscan, flatfielded, zero corrected. (bias = bias70_79 - O corrected) (flat -frame 38- was median smoothed, original divided by it >> 39flat_pix) standard obs was flattened with 19mar0025_pix, W calib with 19_024arc. W calib 037arc (also OZF corrected) F calib 023sens >> 9621_2c.imh 3 apertures #1 SN #2 galaxy nearby (maybe not host) #3 another galaxy nearby. Huge CR messes things up. Fixed in later extraction (below) Tried again : 039_3c. >> 9621_3c >> 9621_sn ascii files: 9621_sn.asc, 9621_gal2.asc, 9621_ap3.asc Gerson thought maybe z=0.5 based on oII @ 5582 - but could be 5577sky line problem ? 19mar0036 ????? >> 19_036_2c combined >> 9621_comb redone again. Sky subtracted first using 'background'. Extracted, combined & fluxed etc >> 9621_mmt_cs same 3 apertures (#1 is object) ascii files: 9621_mmt_cs_ap1.asc 9621_mmt_cs_ap2.asc 9621_mmt_cs_ap3.asc redone again with Saul. Sky not subtracted. > 039_5. -------------------------------------------------
