Pseudo-MSIDs in the engineering archive¶

A small selection of pseudo-MSIDs that do not come in the engineering telemetry stream are also available in the archive. These are:

ACIS DEA housekeeping: status from the DEA (including detector focal plane temperature)
Ephemeris: predictive and definitive orbital (Chandra), solar, and lunar ephemeris values
SIM telemetry: SIM position and moving status
Derived parameters: values computed from other MSIDs in the archive

ACIS DEA housekeeping¶

The ACIS DEA telemeters a variety of useful information that is sent in an event-based format via queries to the processor. The engineering archive reformats those telemetry queries (one per psuedo-MSID) into records that match the engineering archive format where all queries with the same time stamp are place in a single record.

The time sample of these data vary but are typically around once per 16 seconds. Because of what appears to be an issue with CXCDS decom there are frequently bad values at the beginning of an archive file. For this reason it is especially important to perform a fetch with the filter_bad=True setting.

Ephemeris¶

CXC processing generates definitive and predictive ephemeris files for the Chandra, the Moon, and the Sun. Values are given with respect to Earth (ECI). Predictive values are available into the near future while definitive values will be a few weeks behind the present. (Note that daily and 5-minute statistics are only available up to the present time). These values are contained within the following content types:

Content	Object	Type
orbitephem0	Chandra	Predictive
lunarephem0	Moon	Predictive
solarephem0	Sun	Predictive
orbitephem1	Chandra	Definitive
lunarephem1	Moon	Definitive
solarephem1	Sun	Definitive

The psuedo-MSIDs for each of the ephemeris elements is given in the following table, where <CONTENT> is replaced by the appropriate Content value from the previous table.

MSID	Unit	Description
<CONTENT>_x	m	X position (ECI)
<CONTENT>_y	m	Y position (ECI)
<CONTENT>_z	m	Z position (ECI)
<CONTENT>_vx	m/s	X velocity (ECI)
<CONTENT>_vy	m/s	Y velocity (ECI)
<CONTENT>_vz	m/s	Z velocity (ECI)

In addition there is a set of pseudo-MSIDs that provide a number of higher-level definitive angle and distance values that are useful.

Point_Z		Unit Pointing (Z)

HRC Secondary Science and Housekeeping¶

The HRC telemeters a variety of useful information that is sent down in secondary science and housekeeping formats (SS and HK hereafter). The engineering archive reformats those telemetry values to be consistent with the MSFC-1949 specification of HRC SS and HK telemetry. It also facilitates handling invalid data in SS and HK telemetry.

Invalid data¶

Invalid HRC SS and HK telemetry can arise in three ways:

When telemetry format changes there is commanding to change the timing signals used to fill the housekeeping and secondary science rates that can result in invalid data being put in these MSIDs for up to a major frame.
When detectors change or a detector is set to its default configuration the FIFO used to hold the housekeeping an secondary science data gets reset which may result in a single bad sample of data.
The secondary-science byte-shift anomaly causes the occasional portion of the housekeeping and sometimes the rate data to be corrupted.

In the Ska archive the presence of these conditions is tracked in a new pseudo-MSID called HRC_SS_HK_BAD.

The first two of these are detected by looking at “spare” bits in the MSID SCIDPREN (i.e. good data satisfies SCIDPREN=0000xxxx000xxxxx. The least-significant 7 bits of HRC_SS_HK_BAD contain a copy of the 7 bits in SCIDPREN which must be 0 for good data. The following code illustrates detecting conditions (1) or (2):

>>> from Ska.engarchive import fetch
>>> from Chandra.Time import DateTime
>>> dat = fetch.Msid('HRC_SS_HK_BAD', '1999:300', '1999:310')
>>> bad = (dat.vals & 0x7f) > 0
>>> DateTime(dat.times[bad]).date
array(['1999:301:16:10:13.375', '1999:301:16:10:15.425',
       '1999:301:18:16:42.476', '1999:301:18:16:44.526',
       '1999:301:19:20:03.176', '1999:301:19:20:05.226',
       '1999:301:21:28:33.226', '1999:301:21:28:35.276',
       '1999:303:07:13:16.230', '1999:303:07:13:18.280'],
      dtype='|S21')

The third condition is detected by its impact on the MSID 2SMTRATM. If it is less than -20degC or greater than 50degC then the analog housekeeping from the row is marked with bad quality. In this case the HRC_SS_HK_BAD MSID has bit 10 set, which can be detected by a logical-and with 0x0400 (1024).

Querying data¶

For HK telemetry it is sufficient to query the archive using the standard fetch.Msid method which automatically removes bad quality data. This applies for 5-minute and daily stat data as well. For instance:

>>> dat = fetch.Msid('2S2ONST', '2002:200', '2002:250')
>>> dat.plot()

(Source code, png, hires.png, pdf)

For SS the situation is a little different because those do not have the bad quality flags set at the time of data ingest (because the indicators are all in HK). In this case use the fetch.HrcSsMsid method to get a filtered version of the SS MSIDs (2TLEV1RT 2VLEV1RT 2SHEV1RT 2TLEV2RT 2VLEV2RT 2SHEV2RT). For instance to get 5-minute telemetry for 2SHEV1RT use:

>>> dat = fetch.HrcSsMsid('2SHEV1RT', '2002:200', '2002:250', stat='5min')
>>> dat.plot()

Derived Parameters¶

The engineering archive has pseudo-MSIDs that are derived via computation from telemetry MSIDs. All derived parameter names begin with the characters DP_ (not case sensitive as usual). Otherwise there is no difference from standard MSIDs.

Definition¶

Derived parameters are defined by inheriting from the DerivedParameter base class. Each class definition requires three class attributes: content_root, rootparams, and time_step. The time_step should be an integral multiple of 0.25625. In the example below a large number of definition classes have the same content root so another class DerivedParameterThermal has been created to avoid repeating the content_root definition every time.

Each definition class also requires a calc(self, data) method. The data argument will be an MSIDset (dict of fetch MSID objects) with values for each of the rootparams MSIDs. The data values in the MSIDset will be filtered for bad values and aligned to a common time sequence with step size time_step.

class DerivedParameterThermal(base.DerivedParameter):
    content_root = 'thermal'

class DP_EE_DIAM(DerivedParameterThermal):
    """Kodak diametrical encircled energy"""
    rootparams = ['OHRMGRD6', 'OHRMGRD3']
    time_step = 32.8

    def calc(self, data):
        VAL2 = np.abs(1.0 * data['OHRMGRD6'].vals)
        VAL1 = np.abs(1.0 * data['OHRMGRD3'].vals)
        DTDIAM = np.max([VAL1, VAL2], axis=0)
        EE_DIAM = DTDIAM * 0.401
        return EE_DIAM

class DP_P01(DerivedParameterThermal):
    """Zone 1 heater power"""
    rootparams = ['ELBV', '4OHTRZ01']
    time_step = 0.25625

    def calc(self, data):
        VSQUARED = data['ELBV'].vals * data['ELBV'].vals
        P01 = data['4OHTRZ01'].vals * VSQUARED / 110.2
        return P01

class DP_DPA_POWER(base.DerivedParameter):
    """ACIS total DPA-A and DPA-B power"""
    rootparams = ['1dp28avo', '1dpicacu', '1dp28bvo', '1dpicbcu']
    time_step = 32.8
    content_root = 'acispow'

    def calc(self, data):
        power = (data['1dp28avo'].vals * data['1dpicacu'].vals +
                 data['1dp28bvo'].vals * data['1dpicbcu'].vals)
        return power
