New COS/FUV TDS produces more accurate fluxes for data taken
after October 2013
A new COS FUV time-dependent sensitivity (TDS) reference file (ycj1846tl_tds.fits) has been delivered for use in the HST pipeline. This file accounts for the increased slope of the TDS that has been observed since October 2013. Users interested in optimal absolute flux calibration should re-retrieve COS FUV data taken after this date. +----------------------------------------------------------+ | Need help? http://www.stsci.edu/hst/cos/help.html +----------------------------------------------------------+ | To subscribe or unsubscribe to the STAN, send a message | to majordomo@stsci.edu with a blank subject line and | the following in the body: [un]subscribe cos_news | or [un]subscribe stis_news +----------------------------------------------------------+ | The Space Telescope Science Institute is operated by the | Association of Universities for Research in Astronomy, | Inc., under NASA contract NAS5-26555. +----------------------------------------------------------+
