List of FITS header keywords that I use in my analysis, or that we varied as part of the engineering runs, 

exptime
altitude
inr-str
adc-str 
dom-tmp
dom-prs
dom-hum
out-tmp
out-prs
out-hum
date-obs
hst
w_mccovt
w_mcm1t

Do you like the exactly same names for the database column as those here?

We should probably use the same format as the other variables (ie, out_tmp instead of out-tmp). The current ones would work, or if we went them to be more descriptive, we could use something like the following. 

exptime
altitude
instrument_rotation
adc_pa
dome_temperature
dome_pressure
dome_humidity
outside_temperature
outside_pressure
outside_humidity
date_observed
hst
coverpanel_temperature
mainmirror_temperature

OK, thank you. I will propose something and ask you to confirm.

Hi karr & chyan

I changed the column names of mcs_exposure more descriptively like this:

• mcs_frame_id = Column(Integer, primary_key=True, unique=True, index=True, autoincrement=False, comment='MCS frame identifier as generated from Gen2')
• pfs_visit_id = Column(Integer, ForeignKey('pfs_visit.pfs_visit_id'))
• mcs_exptime = Column(REAL, comment='The exposure time for the frame [sec]')
• altitude = Column(REAL, comment='The telescope attitude [deg]')
• azimuth = Column(REAL, comment='The telescope azimuth [deg]')
• insrot = Column(REAL, comment='The telescope instrument rotation angle [deg]')
• adc_pa = Column(REAL, comment='ADC PA at which the exposure started [deg]')
• dome_temperature = Column(REAL, comment='Dome temperature [K]')
• dome_pressure = Column(REAL, comment='Dome pressure [hPa]')
• dome_humidity = Column(REAL, comment='Dome humidity [%]')
• outside_temperature = Column(REAL, comment='Outside temperature [K]')
• outside_pressure = Column(REAL, comment='Outside pressure [hPa]')
• outside_humidity = Column(REAL, comment='Outside humidity [%]')
• mcs_cover_temperature = Column(REAL, comment='MCS cover panel temperature [degC]')
• mcs_m1_temperature = Column(REAL, comment='MCS primary mirror temperature [degC]')
• taken_at = Column(DateTime, comment='The time at which the exposure was taken [YYYY-MM-DDThh-mm-sss]')
• taken_in_hst_at = Column(DateTime, comment='The time (in HST) at which the exposure was taken [YYYY-MM-DDThh-mm-sss]')

Is this all fine with you?
