This file contains the notes from Mike A'Hearn's logbook for the month of May relevant to the IRTF observations of SL/9. Not all of the pages are transcribed below--some are scanned and included as tiff format image files (due to their complexity). The text of those easily transcribed is included below, while the image files are pointed to in the text below. Log notes for months other than January and May have not been located. This document references pages 37 through 40 inclusive. The image files are in a PDS-standard uncompressed TIFF format created from JPEGs which were originally scanned in as TIFF. The back-and-forth conversion has helped reduce the size of the original images from many megabyte sizes down to typically half a megabyte. -------------------------------------------------------------------------- .......................................................................... -------------------------------------------------------------------------- .......................................................................... -------------------------------------------------------------------------- .......................................................................... -------------------------------------------------------------------------- :::::::Page 37::::::: This is the image file may_p37.tif. ----------------------------------------------------------------------------- ----------------------------------------------------------------------------- ----------------------------------------------------------------------------- ----------------------------------------------------------------------------- ----------------------------------------------------------------------------- :::::::Page 38a::::::: This is the image file may_p38a.tif. Note that Page 38a is Page 1 of 2 and is a log of dome flats. The page 38b is not scanned as is 38a because of the trivial nature of transcribing it. ----------------------------------------------------------------------------- ----------------------------------------------------------------------------- ----------------------------------------------------------------------------- ----------------------------------------------------------------------------- ----------------------------------------------------------------------------- :::::::Page 38b::::::: IRTF NSFCAM Observing Log Date 94May11 Observers: A'Hearn + Lisse (+Mark Shure) Page 1of2 --[ed. note, this is actually page 2 of 2] Filename Object Filter Plate_Scale Int._Time #Coadds/#Cycles Time(HST) Comments 175 Lights On A1 Dome Flat K' 0.31 0.125 100/1 1427 Lights On: Flourescents Incandescents 176 Lights Off A1 Dome Flat K' 0.125 100/1 1429 Lights Off: " " 177 A1 Dome Flat J 0.100 100/1 1431 Lights On: " " 178 A1 Dome Flat J 0.100 100/1 1432 Lights Off: " " ----------------------------------------------------------------------------- ----------------------------------------------------------------------------- ----------------------------------------------------------------------------- ----------------------------------------------------------------------------- ----------------------------------------------------------------------------- :::::::Page 39::::::: This is the image file may_p39.tif. ----------------------------------------------------------------------------- ----------------------------------------------------------------------------- ----------------------------------------------------------------------------- ----------------------------------------------------------------------------- ----------------------------------------------------------------------------- :::::::Page 40::::::: 40 1237 Field 2 J Field 3 J sky sub [?] getting progressively worse looks as though chip is getting warm closed cycle cooler tripped off!
