# CTIO Telescope, Filter, and Detector Database 14 Aug 1998 SRH.
#
# Telescope data:
# aperture - From drawings in CTIO facilities manual
# scale - From drawings in CTIO facilities manual and updates
# transmission - Corrects for central obstruction based on drawings
#
# OPTICAL
# -------
# Filter data:
# These were just copied from kpno.dat for consistancy
#
# Detector data:
#
# CTIO ccds
# readnoise - from PFCCD manual by ARW
# dark - from PFCCD manual by ARW
# pixel size - from PFCCD manual by ARW
# DQE - adjusted to give the counts for U=B=V=R=I=20 star
# at the 4.0-m PF tabulated in the PFCCD manual by ARW
#
# BTC - from BTC web page
#
# YaleO - inspired guess based on QE curve on web page
#
# IR
# --
#
# Filter data:
# There is a descrepancy between the count rates in the CIRIM manual
# and the values given for the 4m f/14 tip-tilt system such that
# values scaled by aperture from the 1.5-m OVERESTIMATE object counts
# with the 4m f/14 by a large factor. There is a smaller descrepancy
# scaling counts between the 1.5-m f/8 and 4.0-m f/8. Rob Probst is
# investigating. For the time being I have made two seperate sets of
# filter data.
#
# J,H,Ks,K: for 1.5m f/8. roughtly OK for other non T-T
# Jtt,Htt,Kstt,Ktt: for 4.0m f/14
#
# Detector data:
# CIRIM
# readnoise - from CIRIM manual
# dark - from CIRIM manual
# pixel size - Adjusted to give correct "/pix on 4.0-m f/14
# DQE - used IRIM values from kpno.dat (per D. Joyce)
#
# CCOB
# readnoise - from CCOB manual
# dark - from CCOB manual
# pixel size - Adjusted to give correct "/pix on 4.0-m f/14
# DQE - tweaked to give "correct" counts with 4m f/14
# using Jtt,Htt,Kstt & Ktt
#
# Revised 03 Sept 1998 SRH
#
# 1) New measuremenst by Probst/Blum suggest that the standard filter
# entries do reproduce observed count rates with the 4mf14 tip-tilt
# Apparently the numbers in the manual where wrong. Commented out
# special tt entries pending final confirmation
#
# 2) Revised DQE for CTIO CCD's to reproduce new (lower) 4mpf count rates
# provided by ARW for BVRI. Apparently Moses wrote the wrong numbers on his
# stone tablets. Also adjusted andicam_opt entry since this is just based
# on scaling by the relative QE's of the chips.
#
# 3) For U adjusted to give correct numbers at 0.9-m (no corrector) and
# added transmission(u) entry to 4mpf to correct for PF corrector
# transmission.
#
# 4) inserted transmission(andycam_opt) for 1.0-m to "do this right"
#
# 3) Included extinction for IR filters per Dick Joyce's numbers for KPNO
# With the idea that we should try to be consistant.
#
# Revised 21 Sept 2006 FV
#
# Added Mosaic z' based on estimated values from Arjun Dey.
